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 (50µV max) and near-zero drift over time and temperature at only 35µA (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.
