The OPA363 and OPA364 families are high-performance
CMOS operational amplifiers optimized for very low voltage,
single-supply operation. These miniature, low-cost amplifiers
are designed to operate on single supplies from 1.8V (±0.9V)
to 5.5V (±2.75V). Applications include sensor amplification
and signal conditioning in battery-powered systems.
The OPA363 and OPA364 families offer excellent CMRR
without the crossover associated with traditional complimentary
input stages. This results in excellent performance for
driving Analog-to-Digital (A/D) converters without degradation
of differential linearity and THD. The input commonmode
range includes both the negative and positive supplies.
The output voltage swing is within 10mV of the rails.
The OPA363 family includes a shutdown mode. Under logic
control, the amplifiers can be switched from normal operation
to a standby current that is less than 1μA.
The single version is available in the MicroSIZE SOT23-5
(SOT23-6 for shutdown) and SO-8. The dual version is
available in MSOP-8, MSOP-10, and SO-8 packages. Quad
packages are available in TSSOP-14 and SO-14 packages.
All versions are specified for operation from –40°C to +125°C.
