I have a question about the differential input current for the AD7124-8
The AD7124-8 data sheet states "diferential input current +/-1.5nA (typ)" for the full power mode.
Other similar ADC's available in the market publish the differential input current vs input voltage. For example (Below)
Is this true for the AD7124-8, does the differential input current vary with differential input voltage for the buffered mode or is it a fixed value for any input voltage ?
What are the test conditions for the AD7124-8 below, is this with 0V input for example ?
