These devices are members of the Zero-Drift family of amplifiers which use a proprietary autocalibration 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 railto-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...
