The RES11A-Q1 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-Q1 used to set the amplifier gain.
