PS320/PS321/PS322

Precision, Dual-Supply Analog Switches

Description

Features

ThePS320/PS321/PS322areimprovedhigh-precision,mediumvolt-

age analog switches designed to operate with +3V to +8V power

supplies. The PS320 is a dual, single-pole single-throw (SPST),

normally open (NO) switch. The PS321 has the same pinout as the

PS320butithastwonormallyclosed(NC)switches.ThePS322has

one normally open (NO) and one normally closed (NC) switch per

package. When on, each switch conducts current equally well in

either direction. In the off state, each switch blocks voltages up to

the power-supply rails.

• Low On-Resistance (17W typ.) Minimizes Distortion and

Error Voltages

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

• Split-Supply Operation (±3V to ±8V)

• Improved Second Sources for MAX320/MAX321/MAX322

• On-Resistance Matching Between Channels, 0.2Ωtyp.

• On-Resistance Flatness, <2Ω typ.

• Low Off-Channel Leakage, <5nA @ +85°C

• TTL/CMOS Logic Compatible

• Fast Switching Speed, t_ON<150ns

With ±5V power supplies, the PS320/PS321/PS322 guarantee

<35ΩON-resistance.ON-resistancematchingbetweenchannelsis

within2Ω. ON-resistanceflatnessislessthan4Ωoverthespecified

range. All three devices guarantee low leakage currents (<100pA

@25°C, <10nA @+85°C) and fast switching speeds (t_ON

<150ns). Break-before-make switching action protects against

momentary crosstalk (PS322).

• GuaranteedBreak-Before-Makeaction(PS322)eliminates

momentary crosstalk

• Rail-to-Rail Analog Signal Dynamic Range

• Low Power Consumption, <1.25mW

• MSOP Package Minimizes Board Area

Applications

• Audio Switching and Routing

• Portable Instruments

• Data Acquisition Systems

•· Sample-and-Holds

For single-supply operation the PS323/PS324/PS325 are recom-

mended.

• TelecommunicationSystems

• Battery-Powered Systems
