I have got a question about the AD7902 ADC.
How big is the input resistance of the analog inputs?
In the datasheet I found only a value of 400 Ohm, however is this right?
It seems to be a bit too little.
I'm trying to recreate the experiment in this application note: RF-to-Bits Solution Offers Precise Phase and Magnitude Data for Material Analysis
In this note there is an Amp/Phase panel which can be useful for live updates on the phase differences…
I dont know the EEPROM address for AD7902 and AD9833.
They will be answered by ADI expert guys.
And you should ask them BY ADI model.
Eval board for AD7902 doesnt have EEPROM. Also AD7902 chip alone.
Hi Ryan again
Thanks for the ID information of the EEPROM in the discussion I think that you are the expert to help me in AD7902 + EVAL_SDP-CB1Z in a programmable environment (LabView-MATLAB).
In the executable format of AD7902, when it gives an error…
Here is the LabView source code for the AD7902 / 03.

We are testing the ADC 7902 in the range 0-5V, and we have an issue ADC conversion.
The conversion curve (Volt to counts) is linear in most of the range but there is a windows of…
The standard pitch for a 20 lead quarter size outline plastic (QSOP) package is 25 mil. 25 mil in millimeters is 0.635 mm. The 0.64 mm figure is 25 mil rounded to two digits of precision.
I have got a question about the CS mode of the AD7902 16 bit ADC.
I will use two spi ports for the two adc channels.
MOSI for the CONVST signal, MISO for the SDO and the SCLK.
While using the CS mode, I have got to connect VIO to VDD and SDI…
