3 Description
The OPA330 series of CMOS operational amplifiers
offer precision performance at a very competitive
price. These devices are members of the Zero-Drift
family of amplifiers which use a proprietary auto-
calibration technique to simultaneously provide low
offset voltage (50-μV maximum) and near-zero drift
over time and temperature at only 35 μA (maximum)
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 1.8 V (±0.9 V) and up to 5.5 V
(±2.75 V).
The OPA330 (single version) is available in the 5-pin
DSBGA, 5-pin SC70, 5-pin SOT-23, and 8-pin SOIC
packages. The OPA2330 (dual version) is offered in 3
mm × 3 mm, 8-pin SON, 8-pin VSSOP, and 8-pin
SOIC packages. The OPA4330 is offered in the
standard 14-pin SOIC and 14-pin TSSOP packages,
as well as in the space-saving 14-pin VQFN package.
All versions are specified for operation from –40°C to
125°C.
