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 35

Ω), guaranteed to match to

within 2

Ω 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

loading.
