FSA2269 / FSA2269TS -- Low-Voltage Dual-SPDT (0.4) Analog Switch with Negative Swing Audio Capability

May 2007

FSA2269 / FSA2269TS Low-Voltage Dual-SPDT (0.4) Analog Switch with Negative Swing Audio Capability
Features
0.4 Typical On Resistance (RON) for 3.0V Supply 0.25 Maximum RON Flatness for 3.0V Supply -3db Bandwidth: 50MHz Low-ICCT Current Over an Expanded Control Input Range Packaged in Pb-free 10-Lead MicroPakTM and UMLP Power-Off Protection on Common Ports Broad VCC Operating Range: 1.65 to 4.3V Noise Immunity Termination Resistors in FSA2269TS

Description
The FSA2269 is a high-performance, dual Single-Pole Double-Throw (SPDT) analog switch with negative swing audio capability. The FSA2269 features ultra-low RON of 0.4 (typical) at 3.0V VCC. The FSA2269 operates over a wide VCC range of 1.65V to 4.3V, is fabricated with submicron CMOS technology to achieve fast switching speeds, and is designed for break-before-make operation. The select input is TTL-level compatible. The FSA2269 features very low quiescent current even when the control voltage is lower than the VCC supply. This feature suits mobile handset applications by allowing direct interface with baseband processor general-purpose I/Os with minimal battery consumption. The FSA2269TS includes termination resistors that improve noise immunity during overshoot excursions, off-isolation coupling, or "pop-minimization."

Applications
Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box
