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.
