FSA859 — Dual-Voltage, 0.8Ω SPDT Analog Switch with Power-Off Isolation August 2008 FSA859 — Dual-Voltage, 0.8Ω SPDT Analog Switch with Power-Off Isolation Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ 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 Referenced to VIO Break-Before-Make Enable Circuitry 0.5mm WLCSP packaging ESD Performance 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 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 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 VIO and VCC. The VIO supply operates the control circuitry, allowing for 1.8V (typical) signals on the control pin (Sel). ƒ ƒ ƒ HBM: JESD22-A114, I/O to GND CDM: JESD22-C101 IEC61000-4-2 Contact / Air 8kV 500V 8kV / 15kV Applications Cellular Phone Portable Media Player PDA IMPORTANT NOTE: For additional performance information, please contact analogswitc...
