PS381/PS383/PS385

Precision, 17V Analog Switches

Description

Features

• Low On-Resistance (16Ω typ) Minimizes Distortion

and Error Voltages

• Low Glitching Reduces Step Errors in Sample-and-Holds.

Charge Injection, 3pC typ

The PS381/PS383/PS385 are improved high precision, medium

voltage analog switches designed to operate with +3V to +8V

power supplies.

The PS381 has two normally open (NO) switches. The PS383 is a

dual, single-pole double-throw (SPDT) switch. The PS385 is a

dual, double-pole single-throw (DPST) function. Each switch

conductscurrentequallywellineitherdirectionwhenon. Intheoff

state each switch blocks voltages up to the power-supply rails.

• Single Supply (+3V to +15V) or Split-Supply

(+3V to +8V) Operation

• Improved Second Sources for MAX381/MAX383/MAX385

• On-Resistance Matching Between Channels, 0.2 Ω typ

• On-Resistance Flatness, 1Ω typ

With ±5V power supplies, the PS381/PS383/PS385 guarantee

<30Ω on-resistance. On-resistance matching between channels is

within2Ω. On-resistanceflatnessislessthan4Ωoverthespecified

range. All three devices feature low leakage currents (<2 pA @

• Low Off-Channel Leakage, <2.5nA @ +85 C

• TTL/CMOS Logic Compatible

• Rail-to-Rail Analog Signal Dynamic Range

• Low Power Consumption <1µA

25 C,<2.5nA@+85 C)andfastswitchingspeeds(t

<130ns).

Break-before-make switching action protects against momentary

crosstalk (PS383).

Applications

• Instrumentation, ATE

• Sample-and-Holds

• Audio Switching and Routing

• Telecommunication Systems

• PBX, PABX

These switches are fully specified for single +5V operation,

with <45Ω R , <2Ω R match, and <4Ω R flatness.

For operationbelow5VthePI5A381A/PI5A383A/PI5A385A

are also recommended.
