General Description

The MAX391/MAX392/MAX393 are precision, quad,

single-pole/single-throw (SPST) analog switches

designed to operate at +3V, +5V, or ±5V. The MAX391

has four normally closed (NC) switches, and the

MAX392 has four normally open (NO) switches. The

MAX393 has two NO and two NC switches. All three

devices offer low leakage (100pA max) and fast switch-

sumption is just 1µW—ideal for battery-operated equip-

ment. All devices operate from a single +3V to +15V

supply or from dual ±3.0V to ±8V supplies.

With ±5V supplies, the MAX391/MAX392/MAX393 offer

guaranteed 2

Ω max channel-to-channel matching, 30Ω

over the specified range.

These switches are also fully specified for single +5V

operation, with 2

6

Ω max flatness.

These low-voltage switches also offer 5pC max charge

injection, and ESD protection is greater than 2000V, per

method 3015.7.
