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.
