FSA839: Low-Voltage. 0.8Ω SPDT Analog Switch with Power-Off Isolation
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).
