Description

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.

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

supplies. With +5V, they guarantee <10

Ω on-resistance. On-

resistance matching between channels is within 2

Ω. On-

resistance flatness is less than 4

Ω over the specified range. The

PI5A38X family guarantees fast switching speeds (t

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

QSOP, and PDIP packages for operation over the industrial
