While giving Differential input to the ADC Part No-AD7688,what are the input conditons need to take care.Please send me if you are having reference design.
Attached link is the technical documentation for AD7688.This includes reference designed circuit and other technical details to integrate the component into a system.
I am too referring the same datasheet.I have attached sketch of my doubt.Can you help me to solve my doubt.
I have attached part of my schematic i.e matching network used between differential analog signal and IC OP284,Can you explain me how that matching network useful.
It’s very useful to match the driver/signal amp to your signal sources to receive same power generate from the source. But aside from power level there are some issues to consider like low noise level and low output impedance. We highly recommend to use recommended signal driver in the datasheet. Please see amplifier choices in App Notes page4. The ADA4841-1 and AD8021 are the excellent choices for an ADC driver with pulsar ADCs, high bandwidth and good slew rate. Let me know how you get on.
