UNMATCHED PRICE PERFORMANCE
LOW OFFSET VOLTAGE: 50mV (max)
ZERO DRIFT: 0.25mV/°C (max)
The OPA330 series of CMOS operational amplifiers
offer precision performance at a very competitive
price. These devices are members of the Zerø-Drift

proprietary
LOW NOISE: 1.1mVPP, 0.1Hz to 10Hz
QUIESCENT CURRENT: 35mA (max)
SUPPLY VOLTAGE: 1.8V to 5.5V
RAIL-TO-RAIL INPUT/OUTPUT
auto-calibration technique to simultaneously provide
low offset voltage (50mV max) and near-zero drift
over time and temperature at only 35mA (max) of
quiescent current. The OPA330 family features
rail-to-rail input and output in addition to near flat 1/f
noise, making this amplifier ideal for many
applications and much easier to design into a system.
These devices are optimized for low-voltage
operation as low as +1.8V (±0.9V) and up to +5.5V
(±2.75V).

The OPA330 (single version) is available in the
WCSP-5, SC70-5, SOT23-5, and SOIC-8 packages.
The OPA2330 (dual version) is offered in DFN-8
(3mm × 3mm), MSOP-8, and SOIC-8 packages. The
OPA4330 is offered in the standard SOIC-14 and
TSSOP-14 packages, as well as in the space-saving
VQFN-14 package. All versions are specified for
operation from –40°C to +125°C.
