7.2.4 Summing Amplifier

Figure 7-8 shows the TLVx886 configured as a summing amplifier. This circuit can be used to get a weighted sum of an N number of analog signals. Some applications require a weighted sum of multiple signals coming from different sensors. The low offset and drift performance of the TLVx886 enables the summation of very small signals with high gain. Depending on the choice of resistors, this circuit can provide the average of multiple analog signals. Note that the output of the circuit, as given by Equation 19 is inverted; set the power supplies accordingly.

Equation 19. V O U T = - R F V I N 1 R 1 + V I N 2 R 2 + V I N 3 R 3
