FSA2270T Low-Voltage, Dual-SPDT (0.4Ω) Analog Switch with Negative Swing Audio Capability Features Description 0.4Ω Typical On Resistance (RON) for +3.0V Supply 0.25Ω Maximum RON Flatness for +3.0V Supply -3db Bandwidth: > 50MHz Low-ICCT Current Over Expanded Control Input Range Packaged in 10-Lead UMLP Power-Off Protection on Common Ports Broad VCC Operating Range: 1.65 to 4.3V Noise Immunity Termination Resistors Low Electrostatic Discharge (ESD) - Human Body Model (JEDEC: JESD22-A114) The FSA2270T is a high-performance, dual Single-Pole Double-Throw (SPDT) analog switch with negative swing audio capability. The FSA2270T features ultra-low RON of 0.4Ω (typical) at 3.0V VCC. The FSA2270T 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. Power to GND I/O to GND All other pins The FSA2270T 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 FSA2270T includes termination resistors that improve noise immunity during overshoot excursions, off-isolation coupling, or “pop-minimization.” 16kV 11kV 8kV - Charged Device Model (JEDEC: JESD22-A101) IMPORTANT NOTE: For additional performance information, please contact [email protected].
