FSA5157 0.4Ω Low-Voltage SPDT Analog Switch Features General Description ■ Typical 0.4Ω On Resistance (RON) for +2.7V Supply ■ FSA5157 Features Less than 12μA ICCT Current The FSA5157 is a low on resistance, low-power, Single Pole Double Throw (SPDT) analog switch. This product has been designed for switching audio signals in applications such as cell phones and portable media players. The ultra-low 0.4Ω impedance, sub-μA current consumption, and 1.65V to 4.3V operating voltage range makes this product ideal for battery-powered applications. The FSA5157 also features bi-directional operation and break-before-make functionality. This device is fully specified for operation at 1.8V, 2.5V, and 3.3V. When S Input is Lower than VCC ■ 0.25Ω Maximum RON Flatness for +2.7V Supply ■ 1.0 x 1.45mm 6-Lead MicroPak™ Package ■ Broad VCC Operating Range: 1.65V to 4.3V ■ Low THD (0.02% Typical for 32Ω Load) ■ High-Current Handling Capability (350mA Continuous Current Under 3.3V Supply) ■ Control Logic is 1.8V CMOS Logic Compatible A growing number of applications require the voltage applied to the select input to be lower than the VCC applied. Under this condition, most switches would typically consume over 100μA of current. This would be an unacceptable level for battery-powered applications. The FSA5157 is designed to minimize current consumption under this condition. The ICCT is specified for <12μA under a worst-case condition of VCC = 4.3V and VIN = 1.8V.
