FUNCTION

Analog Guard Channel 1 Normally Open Terminal

Analog Signal Normally Open Terminals

Analog Sense Channel 1 Normally Open Terminal

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-.)

Analog Force Channel 2 Normally Open Terminal

Analog Force Signal Normally Closed Terminal

Analog Sense Channel 2 Normally Open Terminal

Analog Signal Normally Closed Terminal

Analog Guard Channel 2 Normally Open Terminal

Enable Logic-Level Digital Input. Connect to GND to enable all switches.

Logic-Level Digital Inputs. See Truth Tables.

Logic-Level Positive Supply Input. Connect to logic (+5V) supply. Can

be connected to V+ for single-supply operation.

Positive Analog Supply Voltage Input. Internally connected to sub-

strate.

Analog Force Channel Common Terminal

Analog Sense Channel Common Terminal

Analog Guard Channel Common Terminal

* Indicates high-current, low-resistance (force) switch terminal.

Note: NO_, NC_, and COM_ pins are identical and interchangeable. Any may be considered as an input or output; signals pass

equally well in either direction.
