PI5A381A/38P3IA5A/338855AA

Precision Wide Bandwidth Analog Switches

Features

Description

• Single-Supply Operation (+2V to +6V)

• Rail-to-Rail Analog Signal Dynamic Range

• Low On-Resistance (8Ω typ with 5V supply)

Minimizes Distortion and Error Voltages

• R_ONMatching Between Channels, 0.9 Ω typ

• On-Resistance Flatness, 3Ω typ

• Low Charge Injection Reduces Glitch Errors. Q = 7pC typ

• High Speed. t_ON= 8ns typ

• Very Good Off-Isolation: -55dB @ 10 MHz

• Wide -3dB Bandwidth: 230 MHz

The PI5A381/383/385A are dual monolithic analog switches

designed for single-supply operation. These high-precision

devices are ideal for low-distortion audio, video signal switching

and routing.

The PI5A381 is a dual single-pole single-throw (SPST), nor-

mally open (NO) switch. The PI5A383 is a dual single-pole

double-throw (SPDT) switch. The PI5A385 is a dual double-

pole single-throw (DPST), normally open (NO) function.

Each switch conducts current equally well in either direction

when on. When off they block voltages up to the power-supply

rails.

• High-Current Channel Capability: >100mA

• TTL/CMOS Logic Compatible

• Low Power Consumption (0.5µW typ)

• Pin-compatible with DG40X, MAX38X

The PI5A381/383/385 are fully specified with +5V, and +3.3V

supplies. With +5V, they guarantee <10Ω on-resistance. On-

resistance matching between channels is within 2Ω. On-

resistance flatness is less than 4Ω over the specified range. The

PI5A38X family guarantees fast switching speeds (t_ON< 15ns).

Applications

• Audio, Video Switching and Routing

• Battery-Powered Communication Systems

• Computer Peripherals

• Telecommunications

• Portable Instrumentation

• Replaces Mechanical Relays

These products are available in the 16-pin narrow-body SOIC,

QSOP, and PDIP packages for operation over the industrial

(-40^oC to +85 ^oC) temperature range.
