APPLICATIONS

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 5

µA 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.
