0.4 Ohm Low Voltage SPDT Analog Switch

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 0.4W impedance, sub 1A current consumption, and 1.65V to 4.3V operating voltage range makes this product ideal for battery power applications. The FSA5157 also features bi-directional operation and make-before-break functionality. This device is fully specified for operation at 1.8V, 2.5V and 3.3V.
A growing number of applications require the voltage applied to the select input to be lower then the VCC applied. Under this condition, most switches would typically consume over 100A of current. This would be an unacceptable level for battery powered applications. The FSA5157 has been designed to minimize current consumption under this condition. The ICCT is specified for <12A under a worse case condition of VCC = 4.3V and VIN = 1.8V.
