PGA and the gain selections are outlined in Table I. The maximum signal level at

these pins is

±1V with respect to AGND.

4

5

Negative and Positive Inputs for Channel 2 (Voltage Channel). The maximum

differential input voltage is

±660mV for specified operation. The maximum signal

level at these pins is

±1V with respect to AGND.
