9.4 Detailed Design Procedure

The TMUX7212M device can be operated without any external components except for the supply decoupling capacitors. All inputs signals passing through the switch must fall within the recommended operating conditions of the TMUX7212M including signal range and continuous current. For this design example, with a supply of +15 V and -15V, the signals can range from +15 V to -15V when the device is powered. The maximum continuous current can be 220mA.

The application shown in Switching Gain Settings demonstrates how to use the TMUX7212M to control the feedback gain of a precision op-amp. This feedback design can very sensitive to induced voltage and current offsets. The TMUX7212M has a typical On-leakage current of 100 pA which would lead to an accuracy well within 1% of a full scale 1 µA signal, thus minimizing errors from current offsets. The low On-Resistance of the TMUX7212M leads to a low error in the feedback resistance and resulting gain. This additionally minimizes any voltage offsets.
