3 Description
The OPAx994 family (OPA994 and OPA2994) is a
family of high voltage (32V) rail-to-rail input and output
(RRIO) operational amplifiers. These devices offer
excellent AC performance, including a wide unity gain
bandwidth of 24MHz and a high slew rate of 18V/μs,
while only requiring a quiescent current of 1.35mA per
channel.
The OPAx994 family was designed to maintain
stability across a wide range of capacitive loads. For
example, OPAx994 is able to achieve a phase margin
of 50 degrees when driving large capacitive loads of
10 μF with a load resistance of 1MΩ. The OPAx994
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 125mA/
channel, low offset voltage (±350μV, typ), low offset
drift (±2.5μV/°C, typ), and high CMRR of 125dB for
high voltage operation within the main input pair.
This makes the OPAx994 a flexible, robust, and
high-performance op amp for high-voltage industrial
applications.
