7.1 Overview

The OPA2313-Q1 is a low-power, rail-to-rail input and output operational amplifier designed for cost-constrained applications. This device operates from 1.8 V to 5.5 V, is unity-gain stable, and suitable for a wide range of general-purpose applications. The class AB output stage is capable of driving loads greater than 10-kΩ connected to any point between V+ and ground. The input common-mode voltage range includes both rails, and allows the OPA2313-Q1 to be used in virtually any single-supply application. Rail-to-rail input and output swing significantly increases dynamic range, especially in low-supply applications, and makes this device ideal for driving sampling analog-to-digital converters (ADCs).

The OPA2313-Q1 features 1-MHz bandwidth and 0.5-V/µs slew rate with only 50-µA supply current per channel, providing good ac performance at very low power consumption. Low frequency (dc) applications are also well served with a low input noise voltage of 25 nV/√Hz at 1 kHz, low input bias current (0.2 pA), and an input offset voltage of 0.5 mV (typical). The typical offset voltage drift is 2 µV/°C; over the full temperature range the input offset voltage changes only 200 µV (0.5 mV to 0.7 mV).
