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.
