AD7984 is 18bit ADC.
The web site recommends ADR435 or ADR4450 references and AD8031or AD8655 buffer amps.
for example, AD8031 can drive 4 AD7984 references? more?
At this case, AD7984 keeps 18bit feature?
and I would like to know what parameter…
I am trying to talk to EVAL-AD7984-PMDZ from ZedBoard and I am observing unexpected behavior. I am feeding the board with 1 MHz clock with CNV held high for about 30 cycles, but I dont get any readings from SDO pin. It is either high or low all…
The AD7984 is a true differential ADC where the sampled signal is a voltage difference between IN+ and IN- and the signal on this pins are 180 out of phase and range from -Vref to +Vref (-5V to 5V). The Common mode is typically Vref x 0.5…

Dear Technical Support employee!
I'm using an AD7984 to capture the output of a dual slope integrator circuit. I'm using it in /CS mode, 3-wire, with no busy indicator. Sampling at 500 KHz. Vref = 3.3V. SCLK runs at 12 MHz. It's a 16 channel system, but I'm using 16…
I have the ACM sample code(BF609_ACM_AD7984) of BF609 EZ-Lite with me, but not clear with it.
1. The throughout of ADC?
In AD7984 datasheet , the time between conversions of AD7984 is Tcyc(min)=750ns(fcyc=1.33MSPS).
In example code , the width…
If you just want something that works, we also have pre-build images. Those are known to work and can be used as a good starting point if you want to make custom modifcations.
To specify the reference voltage for the ad7984 please use the DT sn…
