9.3 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 TMUX111x allows the system to have multiple gain settings. An external resistor, or utilizing 1 channel always being closed, causes the amplifier to not operate in an open loop configuration. A transimpedance amplifier (TIA) for photodiode inputs is a common circuit that requires gain control using a multi-channel switch to convert the output current of the photodiode into a voltage for the MCU or processor. The leakage current, capacitance, and charge injection performance of the TMUX111x are key specifications to evaluate when selecting a device for gain control.
