General Description

The MAX301/MAX303/MAX305 are precision, dual, high-

speed analog switches. The single-pole single-throw

(SPST) MAX301 and double-pole single-throw (DPST)

MAX305 dualswitches are normally open (NO). The sin-

gle-pole double-throw (SPDT) MAX303 has two NO and

two normally closed (NC) poles. All three parts offer low

on resistance (less than 35Ω), guaranteed to match to

within 2Ω between channels and to remain flat over the

full analog signal range (Δ3max). They also offer low leak-

age (less than 250pA at +25°C and less than 6nA at

+85°C) and fast switching (turn-on time less than 150ns

and turn-off time less than 100ns).

The MAX301/MAX303/MAX305 are fabricated with

Maxim’s new improved silicon-gate process for high

system accuracy. Design improvements guarantee

extremely low charge injection (15pC) and low power

consumption (35µW). A 44V maximum breakdown volt-

age allows rail-to-rail analog signal 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
