OPERATIONAL AMPLIFIER

DESCRIPTION

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

Micro

SIZE 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.

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han­dling and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may de­grade device reliability. These are stress ratings only, and functional opera­tion of the device at these or any other conditions beyond those specified is
not implied. (2) Input terminals are diode-clamped to the power-supply rails.
Input signals that can swing more than 0.5V beyond the supply rails should
be current limited to 10mA or less. (3) Short-circuit to ground one amplifier
per package.
