PA2157
Low RDS_ON SPDT Analog Switch
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.
