DESCRIPTION
●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 (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).
