8 Detailed Description

8.1 Overview

The OPAx206 are the first 36-V, bipolar, e-trim operational amplifiers. These devices use a package-level offset

trim to minimize the offset voltage and offset voltage drift introduced during the manufacturing process. This trim

is performed after the device is assembled to remove any offset errors introduced throughout the manufacturing

process, and trim communication is disabled afterward. The devices feature super beta inputs that decrease the

input bias current and input current noise. The devices also feature input overvoltage protection that protects the

device for input voltages up to ±40 V beyond either supply rail.
