The OPAx994-Q1 family
(OPA994-Q1 and OPA2994-Q1) 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-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 50 degrees
when driving large capacitive loads of 10µF with a load resistance of 1MΩ. 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 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-Q1 a flexible, robust, and high-performance op amp for
high-voltage automotive applications.
