Description

The FSA2271T is a high-performance, dual - single pole

double throw (SPDT) analog switch with negative swing

audio capability. It features ultra-low R

of 0.4

(typical) at 3.0V V

. The FSA2271T operates over a

wide V

range of 1.65V to 4.3V and is fabricated with

sub-micron CMOS technology to achieve fast switching

speeds. Designed for break-before-make operation, the

FSA2271T select input is TTL level compatible.

The FSA2271T features very low quiescent current,

even when the control voltage is lower than the V

supply. This feature is optimized for the mobile handset

applications, allowing direct interface with baseband

processor general-purpose I/Os with minimal battery

consumption.

The FSA2271T includes termination resistors that

improve noise immunity during overshoot excursions,

“pop-minimization,” or off-isolation coupling.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
