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 R ON of 0.8Ω (maximum) at 4.5V V CC and operates over the wide V CC 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). IMPORTANT NOTE: For additional performance info rmation, please contact analogswitch@fairchildsemi.com.
