8.1.3 Fully Differential Amplifier

The RES11A can be used to set the gain of a fully differential amplifier, such as the THP210. The ratiometric matching between the two resistor dividers leads to improved gain matching and CMRR performance for the circuit, when compared to a similar implementation using unmatched discrete resistors.

Figure 8-5 shows a generic schematic representation of a fully differential amplifier driving a differential ADC, with a RES11A used to set the amplifier gain.
