Description

The FSA839 is a high-performance Single-Pole /

Double-Throw (SPDT) analog switch for audio

applications driven by low-voltage (1.8V) baseband

processors or ASICs. The device features ultra-low RON

of 0.8Ω (maximum) at 4.5V VCC and operates over the

wide VCC range of 1.65V to 5.5V. The device is

fabricated with sub-micron CMOS technology to

achieve fast switching speeds and is designed for

break-before-make operation.

The FSA839 interfaces between the low-voltage ASIC

and regular audio amplifiers and CODECs operating up

to a 5.5V supply range. The control circuitry allows for

1.8V (typical) signals on the control pin (Sel).
