Figure 7shows an input buffer circuit example 1. This is a full-differential input buffer circuit with an inverted-amp
(gain :-10dB). The capacitor of 10nF between AIN+ /- decreases the clock feed through noise of modulator, and composes
a 1st order LPF(fc=360kHz) with 22ohm resistor before the capacitor. This circuit also has a 1st order LPF(fc=370kHz)
composed of op-amp. In this example, the internal offset is removed by self calibration. The evaluation board should be
referred about the detail.
