SBOS271A − MAY 2003 − REVISED DECEMBER 2003
Low-Noise, High-Speed, 16-Bit Accurate, CMOS
OPERATIONAL AMPLIFIER
FD EATURES
DESCRIPTION
High Bandwidth: 150MHz
16-Bit Settling in 150ns
Low Noise: 3nV/√Hz
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.

Low Distortion: 0.003%
Low Power: 9.5mA (typ) on 5.5V
Shutdown to 5µA
Unity Gain Stable
Excellent Output Swing:
(V+) − 100mV to (V−) + 100mV

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.
