General Description

The MAX361/MAX362 are precision, quad, single-pole

single-throw (SPST) analog switches. The MAX361 has four

normally closed (NC) switches, and the MAX362 has four

normally open (NO) switches. Both parts offer low channel

on-resistance (less than 85Ω), guaranteed to match within

3Ω between channels and to remain flat over the analog

signal range (∆9Ω max). Both parts also offer low leakage

(less than 500pA at +25°C and less than 4nA at +85°C) and

fast switching (turn-on time less than 250ns and turn-off time

less than 170ns).

The MAX361/MAX362 are fabricated with Maxim’s new

improved 44V silicon-gate process. Design improve-

ments guarantee extremely low charge injection

(10pC), low power consumption (35µW), and electro-

static discharge (ESD) greater than 2000V. The 44V

maximum breakdown voltage allows rail-to-rail analog

signal handling capability.

These monolithic switches operate with a single positive

supply (+10V to +30V) or with split supplies (±4.5V to ±20V)

while retaining CMOS-logic input compatibility and fast

switching. CMOS inputs provide reduced input loading.
