Overview

Low Supply Signal Bypass IC Product Preview FSA557 The FSA557 integrates 0.
3 W depletion and enhancement mode switches to provide a signal bypass solution when batteries of wireless devices are low or have no charge left.
In addition, an optional slow gradual transition is included to suppress any undesirable artifacts (ex: click and pop) when switching between signal sources.
The depletion technology allows the device to conduct signals when there is no VDD available and to isolate signals when VDD is present.
The FSA557 is 5.
5 V tolerant and can pass or isolate negative signal swings down to −1.
5 V.
Features • Dual Depletion Switches ♦ Normally Closed when VDD < 0.
5 V ♦ VSW: −1.
5 V to +5.
