Abstract
A circuit and a system that uses the circuit for connecting a plurality of input channels to a receiving device. The circuit includes a plurality of DMOS switches, each of which connects a respective one of the input channels to the receiving device in response to a respective control signal. The control signals are referenced to a ground signal. Each input channel includes a common mode voltage that is non-referenced to the ground signal. The circuit also includes a switch driver that generates the control signals such that the input channels are activated one at a time.
