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 35V/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
10µF 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, typical), low offset drift (±2.5µV/°C, typical), 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.
