EVM Analog Interface

2 EVM Analog Interface
The ADS8168EVM is designed for easy interfacing to analog sources. The 12-position, dual-row, pin
header connector, J3, provides convenient access to channels Ain1–Ain8 and Ain–COM of the device. In
addition, 3 SMA connectors, IN1, IN2, and IN9 provide a high quality connection to channels Ain1, Ain2,
and Ain-COM, respectively. For channels 1 and 2, a high-impedance input signal conditioning driver circuit
is provided. On all channels, a resistor-capacitor combination helps to provide a stable voltage on the
input of the ADS8168 multiplexer inputs.
