9.2 Typical Application – Switched Gain Amplifier

Switches and multiplexers are commonly used in the feedback path of amplifier circuits to provide configurable gain control. By using various resistor values on each switch path the TMUX7212M allows the system to have multiple gain settings. An external resistor, or utilizing 1 channel always being closed, ensures the amplifier is not operating in an open loop configuration. The leakage current, On-Resistance, and charge injection performance of the TMUX7212M are key specifications to evaluate when selecting a device for gain control.
