General Description
The FSA2859 is a high-performance Double-Pole / Double-Throw (DPDT) analog switch for audio applications driven by low voltage (1.8V)
baseband processors or ASICs. The device features ultra-low RON of 0.8W (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 FSA2859 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 VIO and VCC. The VIO supply operates the control circuitry, allowing for
1.8V (typical) signals on the control pin (Sn).
