Analog input pins R1
IN
and R2
IN
have ± 25-V overvoltage protection. The input signal must be referenced to
AGND1. This referencing minimizes ground-loop problems typical to analog designs. The analog input should be
driven by a low-impedance source. A typical driving circuit using the OPA627 or OPA132 is shown in Figure 40 .
