Quad, 1.8-V, 35-µA, micropower, precision, zero drift CMOS op amp

The OPA330 series of CMOS operational

amplifiers offer precision performance at a very competitive price. These devices are members of

the Zerø-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.
