3 Description

The OPAx994-Q1 family (OPA994-Q1 and OPA2994-

Q1) is a family of high voltage (24 V) rail-to-rail

input and output (RRIO) operational amplifiers. These

devices offer excellent AC performance, including a

wide unity gain bandwidth of 25-MHz and a high

slew rate of 18 V/μs, while only requiring a quiescent

current of 1.25 mA per channel.

The OPAx994-Q1 family was designed to maintain

stability across a wide range of capacitive loads. For

example, OPAx994-Q1 is able to achieve a phase

margin of 60 degrees when driving large capacitive

loads of 10 μF with a load resistance of 1 MΩ.

The OPAx994-Q1 is designed with compensation

architectures that mitigate sustained ringing for large

capacitive loads. This allows for reliable performance

and ease of design for systems that have large,

varying, or unknown capacitive loads.

These devices also offer excellent DC precision,

including a high short-circuit output current of 150 mA/

channel, low offset voltage (±200 μV, typ), low offset

drift (±0.17 μV/°C, typ), and high CMRR of 135 dB

for high voltage operation within the main input pair.

This makes the OPAx994-Q1 a flexible, robust, and

high-performance op amp for high-voltage automotive

applications.
