Hi everyone,
In our design we are using AD8221ARMZ differential amplifier, when we are applying differential voltages at input side it's shows output always -4.291. what is the reason, please suggest me.
For example i am applying -IN=3.280
+IN=2.527
Vout=-4.291
Thanks,

Hi !
I have a question about ADV7480 THERMAL RESISTANCE.
I think this is correct but I want to confirm this.
So this means if our customer use ADV7480 with HDMI ,
ΨJT*WTOTAL will be 0.8deg.
Is this correct?
Best regards.

Hi !
I have some questions about ADV7480.
Q1)
I was checking ADV7480 eval board.
And there was no pull-up resistor.
But ADV7611 eval board has pull-up resistor.
And also ADV7611 manual says ADV7611 HPD pin is open drain type.
So I think ADV7480 HPD pin is not open drain type.
Some kind of buffer is in the pin.
Is this correct?
Or does ADV7480 HPD pin have open drain circuit?
Q2)
When the supply power is off to ADV7480 , can ADV7480 output HPD "H" when the HDMI connecter is connect?
I tried this with ADV7480 eval board and HPD was "H" only the supply power is ON.
Best regards

Hello,
i want to generate a Sine Wave with AD9958 but receive no output.
The Chip is connected like the Chip on the Evaluation Board, except that i only use the SPi Pins.
SDIO_0 and SDIO_2 are accessable while SDIO_1 and SDIO_0 are pulled to ground.
CS is connected to Ground because i only use one DDS.
The used Code is attached and the few commands i changed are highlighted.
I also attached my schematic, but i stayed as close to the evaluation board as possible for my application so i doubt that there are problems but maybe im wrong.
How can i check if the Chip got damaged while soldering? Is there a possible way to check this?
The Chip seems to trigger the Crystal correctly but as mentioned before i don't see any output.
Thanks for your help

In FDDI mode can the AD9361 simultaneously TX (on one channel) and RX (on the other)?
Hi!
The AD7492 datasheet says that the internal 2.5 V reference is available for external referencing. The EVAL-AD7492SDZ User Guide showing the connection of REF OUT with +input of the AD8021AR what have typical Input Bias Current 7.5 uA.
I want to connect the voltage divider (750 kOhm+32 kOhm) to the output REF OUT of the AD7492BRUZ and join the midpoint of the divider with a non-inverting input of the AD8066. Could this load affect the AD7492BRUZ?
I have questions about AD7175-2, but I beleive they would also valid for AD7172-2 and AD7177-2, so the answers would be relevant for their users too.
The b) forces to use 5 V external refernce, which is disadvantageous for measurement on channel 1. Luckily, the ADC has inetrnal 2.5 V reference, which could be used on channel 1 to bring it closer to optimum range. Would it make sense to do so?
I may have further questions as I move on with the programming.
I can use the ACE software (Analysis | Control | Evaluation (ACE) Software | Design Center | Analog Devices ) to control and configure the EVAL-AD5767 DAC (AD5767 Datasheet and Product Info | Analog Devices) using the SDP-CB1Z (http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-platforms/sdp.html ).
I was wondering if it was possible to configure and control the AD5767 DAC using an external program (e.g. Labview) or interface using .NET similar to the DAC software suite (High-Speed DAC Software Suite [Analog Devices Wiki] ).
Are examples available for this?
Thanks for your help
Hi, is it possible to use the parallel ports of HMC960 only, without SPI interface. We dont have SPI on our board. Thanks.
I'm trying to communicate with AD5410 and not getting the response I'm expecting. I'm currently just trying to set the control register and read back the control register but I'm not getting any response. Also not seeing 4ma on the output as I would expect if the configuration were being applied.
Attached is timing diagram for SPI and schematic.
Hi,
i am altera user and can not use xilinx but i have seen all the support in xilinx only.
I wanted to intaerface AD9364 with Nios2 processor. What i understand is that in SW i have to use
no os driver but how to create the HDL for QSYS to integrate it with Nios2? I don't want to use Linux and
hard processor.
I wanted to know that does internal LO support from 70MHz to 6 GHz?

I have the virtual machine with Windows7 which have VDSP++ 5.1.2 and CCES. The emulator driver (ADZS-HPUSB-ICE) works fine, but when I suspend the program the latency is very long.
I have installations of Windows10 and Windows7 on different PC targets which have only CCES.
The emulator driver (ADZS-HPUSB-ICE) are available only if I do:
bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
Now my target OS works in test mode.
What do I do that Windows work in the normal mode?
Hi,
We are planning to use ADM1272 for one our product,that will have options for varying the current limit as per user requirement. The Iset pin provided with the IC holds good for varying the current on the go,but need some clarity on whether the current sense voltage across the sense resistor can be set for a minimum limit of 2.5mV for both ISET and ISTART and whether the PMbus provided as part of the IC can be left unconnected,since we dont require this option.

Application:
I enabled all 4 channels in AD7175-2, and set the ODR to 17,857SPS.
Using single conversion mode to sample all the channels by writing to ADC Mode register with 0x4010.
Question:
The settling time of first channel ( time after writing the ADC Mode register to the first falling edge of RDY) is about 78us.
Settling time of the later 3 channels( time between adjacent falling edge of RDY) is 56us, which is the same as the datasheet discribed.
So why the first settling time takes 20us more？
I can try to blogging my migrating to CCES from VDSP++.
I have VDSP++ project which use C++.
Now I did the superfast interrupt handlers in CCES my peripheries work well (about this I blog later).
When I started my project I noticed (https://ez.analog.com/thread/9912) that fract C win class fract C++ so I decided use built-in functions because I want to take fract support in C++ with maximum performance.
At that time I noticed next:
int x = 0.5r; // x = 0x40000000
and I started it to use I'm my project.
I declared the variable as integer but I used built-in functions so I got fract support in C++.
But when I am migrating to CCES from VDSP++ I want to start my project with minimum modifications
must know the paragraph "Data Type Conversions and Fixed-Point Types".
So now I must use Bit-Pattern Conversion Functions: bitsfx and fxbits:
int x = bitsr(0.5r); // x = 0x40000000
Now, I want to control the ADV7482 chip through I2C, and I am sure that the I2C IO Map write address of ADV7482 is 0xE0, because the ALSB pin is logic 0. But When I start up my system and try to write registers through I2C, my I2C analyzer always notes me the ADV7482 is NACK. So I want to know I can I know the chip is already powered up.
Dear Experts;
My customer is using ADV7619, everything is well when they use the same EDID content for the both PortA and PortB;
now they want to support different EDID content on PortA and PortB as they will connenct the two ports to diffetent HDMI source for different resolution/format;
could you give me an example to do this function as i only have the script file for the one EDID content? Thanks;
Best Regards

Hello everyone.
I'm a beginner user of ADSP21489 Sharc DSP.
I'm trying to modificate (and compile) the ADSP21489 CCES template project for let me to change the SPDIF trasmission rate on the fly, when DSP receive a command from a uC.
Using SRC1 and PCGs I'm able to generate all different rate but only if this setting is done at the startup of the processing.
How to change PCGs parameters when the processing is running?
How to change SRU configuration when the processing is running?
Thanks in advance.
The selection in the dropdown list control on TES' "Configuration" tab cannot be changed. Only the options "Select" and "OBSON" are available when the list drops down, and only the latter can be selected. I also note that no means is provided to select the desired Observation Rx channel (e.g., Sniffer A, B, or C).
Additionally, the "Rx Chnl" dropdown list also has an unselectable "Select" option, and the "RXOFF" option (visible in the illustration of this tab in UG-992) is not present in the list.
I am running 64-bit Windows 7 Professional SP1 and TES v2.0.62.
