7.4 Switchable Op Amp Gain Setting

One example application of the multiplexer is to change an Op Amp from unity gain setting to an inverting amplifier configuration. Utilizing a switch like the TMUX1219 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.
