Precision, Quad, SPST Analog Switches
General Description
Features
The MAX391/MAX392/MAX393 are precision, quad,
single-pole/single-throw (SPST) analog switches
designed to operate at +3V, +5V, or 5Vꢀ The MAX391
has four normally closed (NC) switches, and the
MAX392 has four normally open (NO) switchesꢀ The
MAX393 has two NO and two NC switchesꢀ All three
devices offer low leakage (100pA max) and fast switch-
ꢀ Low On-Resistance, 20Ω Typical
ꢀ Guaranteed On-Resistance Match Between
Channels, <2Ω
ꢀ Guaranteed On-Resistance Flatness Over Signal
Range, 4Ω Max
