8.1 Overview

The OPA2863-Q1 is a low-power, 50‑MHz, rail-to-rail input and output (RRIO), bipolar, voltage-feedback operational amplifier with a voltage noise density of 5.9 nV/√Hz and 1/f noise corner at 25 Hz. The OPA2863-Q1 works with a wide-supply voltage range of 2.7 V to 12.6 V, and consume only 700 μA quiescent current. The OPA2863-Q1 operates with a 2.7 V supply, is RRIO capable, consumes low-power, which makes this a great amplifier for 3.3‑V or lower-voltage applications that require excellent ac performance. The main and auxiliary input stages of the amplifier are matched for gain bandwidth product (GBW), noise, and offset voltage and designed for applications that require wide dynamic input range and good SNR.

The device includes an overload power limit feature which limits the increase in quiescent current with over-driven and saturated outputs to either of the supply rails. For more details of this overload power limit feature, see Section 8.3.2.1. The output of the amplifier is protected against short-circuit fault conditions.
