_______________General Description

The MAX351/MAX352/MAX353 are precision, quad,

single-pole single-throw (SPST) analog switches. The

MAX351 has four normally closed (NC), and the MAX352

has four normally open (NO) switches. The MAX353 has

two NO and two NC switches. All three parts offer low on

resistance (less than 35

Ω), guaranteed to match within 2Ω

between channels and to remain flat over the analog signal

range (

∆3Ω max). They also offer low leakage (less than

250pA at +25°C and less than 6nA at +85°C) and fast

switching (turn-on time less than 175ns and turn-off time

less than 145ns).

The MAX351/MAX352/MAX353 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 electrostatic discharge

(ESD) greater than 2000V. The 44V maximum breakdown

voltage allows rail-to-rail analog signal handling.

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.
