FSA5157
0.4: Low Voltage SPDT Analog Switch (Preliminary)
General Description
Features
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 Ohm
impedance, sub 1 A 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.
