How dual-supply analog switches can operate with a single 3V or 5V
supply


Abstract: By adding a voltage doubler and voltage inverter, a single 3V or 5V power supply can produce the voltages necessary
to improve the performance on a dual voltage analog switch. With the higher power supplies and wider range, the on-resistance
and timing performance are enhanced.

By adding a single component to a 3V-only or 5V-only board, you can operate conventional CMOS analog switches with
performance approaching that specified with dual ±15V supplies. This simple mo
