UNMATCHED PRICE PERFORMANCE

The OPA330 series of CMOS operational amplifiers

offer precision performance at a very competitive

•

LOW OFFSET VOLTAGE: 50mV (max)

price. These devices are members of the Zerø-Drift

•

ZERO DRIFT: 0.25mV/°C (max)

family

of

amplifiers

which

use

a

proprietary

•

auto-calibration technique to simultaneously provide

•

QUIESCENT CURRENT: 35mA (max)

low offset voltage (50mV max) and near-zero drift

over time and temperature at only 35mA (max) of

•

SUPPLY VOLTAGE: 1.8V to 5.5V

quiescent current. The OPA330 family features

•

RAIL-TO-RAIL INPUT/OUTPUT

rail-to-rail input and output in addition to near flat 1/f

•

INTERNAL EMI FILTERING

noise,

making

this

amplifier

ideal

for

many

applications and much easier to design into a system.

•

microSIZE PACKAGES: WCSP, SC70, QFN

These

devices

are

optimized

for

low-voltage

operation as low as +1.8V (±0.9V) and up to +5.5V

APPLICATIONS

(±2.75V).

•

BATTERY-POWERED INSTRUMENTS

The OPA330 (single version) is available in the
