9.2.2 Input Control for Power Amplifier

Another application of the TMUX1219 is for input control of a power amplifier. Utilizing a switch allows a system to control when the DAC is connected to the power amplifier, and can stop biasing the power amplifier by switching the gate to GND. Figure 19 shows the TMUX1219 configured for control of the power amplifier.
