We have experienced a string of failures with this component after replacing some of the surrounding discrete components leading to the amplifier. All typical ESD precautions aside, is anyone aware of particular sensitivities when performing hand (not…
The datasheet suggests a power sequence for the single-supply implementation. Are there any timing requirements between each event?
Hi,
I would like to use ADAQ7980.
I have two questions.
#1 What is the power supply for Reference Buffer?
#2 It is written that Gain is stable with unity gain on page 28 of datasheet.
And, Open-Loop Gain is written as 111 dB.
How much can a…

Hi bernico,
Which interface mode are you using? Depending on the (3-/4-wire) mode you are using, You can try putting a 47kΩ pull-up resistor tied to VIO as shown in the datasheet, so all the parts connected to FPGA or any other digital host should have…
So, I have three question.
#1 What is the total current consumption when Sampling rate is reduced to its limit?
(ADC Driver, Reference Buffer, LDO enable)
#2 What is the total current consumption when Sampling…
Hi, Tyler
Thank you for the document. I will consider it as a reference.
I forgot the product ADAQ7980. Let me think together with the sampling rate.
I think it will be useful.
Thank you very much.
Best regards,
Yuya
That project was created in ISE 14.4. Currently we are not planning to port it to Vivado. What you can do is to use the ad7980 old IP source (https://github.com/analogdevicesinc/fpgahdl_xilinx/tree/master/cf_lib/edk/pcores/axi_ad7980_v1_00_a) and…
