8 Detailed Description

8.1 Overview

The OPAx205 are the first 36-V bipolar, e-trim operational amplifiers that uses 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 has been assembled to remove any offset errors introduced throughout the

manufacturing process, and trim communication is disabled afterward. These devices also feature super-beta

inputs that decrease the input bias current and input current noise.

The following section shows the simplified diagram of the OPAx205.
