DESCRIPTION
The OPA300 and OPA301 series high-speed,
voltage-feedback, CMOS operational amplifiers are
designed for 16-bit resolution systems. The
OPA300/OPA301 series are unity-gain stable and
feature excellent settling and harmonic distortion
specifications. Low power applications benefit from low
quiescent current. The OPA300 and OPA2300 feature
a digital shutdown (Enable) function to provide
additional power savings during idle periods. Optimized
for single-supply operation, the OPA300/OPA301
series offer superior output swing and excellent
common-mode range.
The OPA300 and OPA301 series op amps 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. The OPA2300 is available
in MSOP-10, and the OPA2301 is available in SO-8 and
MSOP-8. All versions are specified over the industrial
temperature range of −40°C to +125°C.
