2.1 Connectors for Differential Signal Source

The ADS9110EVM is designed for easy interfacing to an external analog differential source via a subminiature version A (SMA) connector or 100-mil headers. J7 and J3 are SMA connectors that allow analog source connectivity through coaxial cables. Also, 100-mil jumper cables or mini-grabbers can be used to connect analog sources to the J4:2 and J6:2 pins.

Note:

The input does not support single-ended signals. The external source must be differential or balanced keeping the negative and positive inputs to the board symmetric such that Vs(+) = –Vs(–) at any given time.
