Switchable Operational Amplifier Gain Setting

One example application of the TMUX1219 is to change an Op Amp from unity gain setting to an inverting amplifier configuration. Utilizing a switch allows a system to have a configurable gain and allows the same architecture to be utilized across the board for various inputs to the system. Figure 17 shows the TMUX1219 configured for gain setting application.
