8.1 Overview
The OPAx172-Q1 family of operational amplifiers provide high overall performance, making the devices ideal for
many general-purpose applications. The excellent offset drift of only 1.5 µV/°C (maximum) provides excellent
stability over the entire temperature range. In addition, the family offers very good overall performance with high
CMRR, PSRR, A_OL, and superior THD.
The Functional Block Diagram section shows the simplified diagram of the OPA172-Q1 design. The design
topology is a highly-optimized, three-stage amplifier with an active-feedforward gain stage.
