DESCRIPTION
The OPA300 and OPA301 high-speed, voltage-feed-
back, CMOS operational amplifiers are designed for
16-bit resolution systems. The OPA300 and OPA301
are unity-gain stable and feature excellent settling and
harmonic distortion specifications. Low power applica-
tions benefit from low quiescent current. The OPA300
features digital shutdown (Enable) function to provide
additional power savings during idle periods. Optimized
for single-supply operation, the OPA300 and OPA301
offer superior output swing and excellent common-
mode range.
The OPA300 and OPA301 have 150MHz of unity-gain
bandwidth, low 3nV/√Hz voltage noise, and 0.1%
settling within 30ns. Single-supply operation from 2.7V
(±1.35V) to 5.5V (±2.75V) and an available shutdown
function that reduces supply current to 5µA are useful
for portable low-power applications. The OPA300 and
OPA301 are available in SO-8 and SOT-23 packages,
and are specified over the industrial temperature range
of −40°C to +125°C.

(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.
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.
