7 Detailed Description

7.1 Overview

The TLV2186 operational amplifier combines precision offset and drift with excellent overall performance, making

the device a great choice for a wide variety of precision applications. The precision offset drift of only 0.1 µV/°C

provides stability over the entire operating temperature range of –40°C to +125°C. In addition, this device offers

high-impedance power supplies require decoupling capacitors close to the device pins. In most cases, 0.1-µF

capacitors are adequate. See the Layout Guidelines section for details and a layout example.

The TLV2186 is part of a family of zero-drift, MUX-friendly, rail-to-rail output operational amplifiers. This device

operates from 4.5 V to 24 V, is unity-gain stable, and is designed for a wide range of general-purpose and

precision applications. The zero-drift architecture provides ultra-low input offset voltage and near-zero input offset

voltage drift over temperature and time. This choice of architecture also offers outstanding ac performance, such

as ultra-low broadband noise, zero flicker noise, and outstanding distortion performance when operating below

the chopper frequency.
