FSA859 — Dual-Voltage, 0.8Ω SPDT Analog Switch with

Power-Off Isolation

Features

Description

The FSA859 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 R_ON

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

wide V_CCrange 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.

Power-Off Isolation (V_CC=0V)

0.8Ω Maximum On Resistance (R_ON) for 4.5V V_CC

0.25Ω Maximum R_ONFlatness for 4.5V V_CC

Broad V_CCOperating Range: 1.65V to 5.5V

Fast Turn-On and Turn-Off Times

Control Input Referenced to V_IO

Break-Before-Make Enable Circuitry

0.5mm WLCSP packaging

The FSA859 interfaces between the low-voltage ASIC

and regular audio amplifiers and CODECs operating up

to the supply range of 5.5V through the dual-voltage

supplies of V_IOand V_CC. The V_IOsupply operates the

control circuitry, allowing for 1.8V (typical) signals on

the control pin (Sel).
