8.1 Overview

The TLV27L2-Q1 device is a micropower, rail-to-rail output, operational amplifier. This device operates from 2.7 V to 16 V, is unity-gain stable, and is suitable for a wide range of general-purpose applications. The class AB output stage is capable of driving ≤ 10-kΩ loads connected to any point between V+ and ground. The input common-mode voltage range includes the negative rail and allows the TLV27L2-Q1 device to be used in virtually any single-supply application from 2.7 V to 16 V. The typical supply current of 7 µA makes the TLV27L2-Q1 device an excellent choice for battery operated systems.

8.3.1 Offset Voltage

The output offset voltage (V_OO) is the sum of the input offset voltage (V_IO) and both input bias currents (I_IB) times the corresponding gains. Use the schematic and formula in Figure 25 to calculate the output offset voltage.
