FSA5157L6X Datasheet PDF - Fairchild

●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 0.4

●W

●impedance, sub 1µA 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.

●A growing number of applications require the voltage applied to the select input to be lower than the V

●CC

●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
