DESCRIPTION

The PA2157 is a single, bidirectional, single-pole/ double-

throw (SPDT) CMOS analog switch that is designed to

operate from a single +1.8V to +5.5V supply. It features

high-bandwidth (300MHz) and low on- resistance (4.5Ω

TYP), Targeted applications for audio switching.

The PA2157 features guaranteed on-resistance matching

(0.3Ω MAX) between switches and guaranteed on-

resistance flatness over the signal range (2.3Ω TYP).

This ensures excellent linearity and low distortion when

switching audio signals.

PA2157 is available in a SC70-6 package.
