1) Measured VOCM and differential input to ADC3422 with keysight 34470A (7.5 digit DMM), the voltage is quite stable, voltage change < 1mV
2) Measured power supply +/-5V and 1.8V for analog with keysight 34470A, the voltage change < 1mV.
3) Removed…
Part Number: ADC3422 I implemented the PRBS engine of previous thread some time ago.
Now I'm acquiring samples from a real chip, but these doesn't correspond to numbers generated by PRBS...
On original thread I noted that data value is obtained…
Part Number: ADC3422 Hello,
Any one has more ideas on it?

Part Number: ADC3422 Hi,
for in circuit testing purposes, we would employ the integrated PRBS generator for test sample data, which can be enabled on registers 0A and 0B.
We need to know details about PRBS generator, i.e. its internal structure, polyn…
Part Number: ADC3422 Hello,
In datasheet, the dc accuracy is in below table.
So if using this adc3422 to measure 2V input voltage.
the worst case error will be , 25mV offset and 2%FS = 40mV
so total error will be 25mv+40mV = 65mV.
Let me know if above…
Part Number: ADC3422 I don't see anything in the datasheet relating the ADC code to the reference voltage. For example, I set the output to be in binary mode and use a signal-ended input, then INP= Vcm = 0.95. If INM = 0.95, the voltage difference…

Part Number: ADC3422 Hi Team,
Good day! Our customer is asking how ADC3422 can be interface with a spartan 6 FPGA. If possible could you please provide Verilog files or some project for ADC3422?
Thank you so much in advance.
Best regards,
Jonathan
