Analog Signal Common Terminals. COM2 and COM3 are low-resis-
tance (force) switches on the MAX4555. COM1 is a low-resistance
(force) switch on the MAX4556.
Analog Force Channel 1 Normally Open Terminal
Analog Signal Normally Closed Pins. NC2 and NC3 are low-resistance
(force) switches.
Analog Force Signal Normally Open Terminal
Negative Analog Supply Voltage Input. Connect to GND for single-
supply operation.
Ground. Connect to digital ground. (Analog signals have no ground
reference; they are limited to V+ and V-.)
