FSA839 — Low-Voltage, 0.8Ω SPDT Analog Switch with Power-Off Isolation January 2009 FSA839 — Low-Voltage, 0.8Ω SPDT Analog Switch with Power-Off Isolation Features Power-Off Isolation (VCC=0V) 0.8Ω Maximum On Resistance (RON) for 4.5V VCC 0.25Ω Maximum RON Flatness for 4.5V VCC Broad VCC Operating Range: 1.65V to 5.5V Fast Turn-On and Turn-Off Times Control Input Switching Thresholds Independent of VCC Break-Before-Make Enable Circuitry 0.4mm WLCSP Packaging ESD Performance 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). - HBM per JESD22-A114, I/O to GND: CDM per JESD22-C101: IEC61000-4-2 Contact / Air: 8kV 500V IMPORTANT NOTE: For additional performance information, please contact analogswitch@fairchildsemi.com. 8kV / 15kV Applications Cellular Phone Portable Media Player PDA Ordering Information Part Number FSA839UCX Operating Top Mark Temperature Range -40°C to +85°C N3 Eco Status Green Package 6-Ball WLCSP, 0.4mm Pitch Packing Method Tape and Reel For Fairchild’s definition of “green” Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html.
