Part Number: ADS8920B Other Parts Discussed in Thread: ADS8902B , Hi there,
We are using the ADS8902B ADC in one of our designs and would like to get some clarification on the timing of SDO.
Below are screenshots from the ADS8920B datasheet:

Part Number: ADS8920B Hi,
Is there an example project which shows how to interface ADS8920B using SPI peripheral? I briefly looked into your datasheet but it was not clear for me on how to interface a SPI master to talk to ADS8920B.
Regards,
Ma…
Part Number: ADS8920B Hello team,
Can we operate ADS8920B in 16-bit frame although it is impossible to wright resisters? If yes, can we use both data transfer zone; zone-1 and zone-2?
Best regards, Iwata Etsuji
Part Number: ADS8920B Other Parts Discussed in Thread: ADS8900B I've been trying to simulate a circuit taking low and higher level photodiode currents and digitizing them with the ADS8920B. Attached is the schematic I am using. It works fine when the…
Part Number: ADS8920B Other Parts Discussed in Thread: ADS8922B , ADS8924B Hi Team, I have a question regarding the KICKBACK Filter design in the ADS892xB data sheet. According to the datasheet it has three sampling rates. ADS8920B: 1-MSPS =1Mhz ADS8922B…
Part Number: ADS8920B Hi.
We are using the above converter in QSPI mode with the data being read by an FPGA.
There is a very odd fault in that the data lines all read the same value (either all ones or all zeros depending upon Vin) in each of the…
Part Number: ADS8920B Hello team,
Small signal bandwidth of ADS8920B is specified with 23MHz.
Does ADS8920B support under-sampling?
Could you share noise performance data up to 1.75MHz if you have? such like datasheet figure 28.
Best regards,
Hi Ian,
Take a look at section 7.5.3 in the datasheet which describes two data transfer time zones (Zone 1 and Zone 2). Zone 1 is the standard SPI transfer zone; Zone 2 is referred to as part of Enhanced SPI. MultiSPI refers to multiple SDO lines, but…
Part Number: ADS8920B Hello,
I have a question for ADS8920B. Its Vcm range analog input is specified as Vre/2 +- 0.1V. What kind of problem could occur if analog input Vcm is out of this range?
Regards, Oba
Part Number: ADS8920B Hi team,
When we will check the SPI W/R validity with MCU, can we operate ADS8920B w/o RVDD and VREF? Can we run ADS820B in the following condition?
RVDD: open VREF: open AIN: shorted REFBUFOUT: open GND/REFM1: SGND RST: DVDD…
