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.
