8.1.1 Discrete Difference Amplifier

The RES11A is commonly used to implement a simple difference amplifier. The ratiometric matching between the two resistor dividers improves CMRR performance and gain drift for the circuit, when compared to a similar implementation using unmatched discrete resistors. The basic circuit is shown in Figure 8-1.

Equation 13. V OUT = V IN+ − V IN− × R G R I N + V REF
