The OPA333 series of CMOS operaTIonal amplifiersuses a proprietary auto-calibraTIon technique tosimultaneously provide very low offset voltage (10 μ Vmax) and near-zero drift over TIme and temperature.These miniature, high-precision, low quiescentcurrent amplifiers offer high-impedance inputs thathave a common-mode range 100mV beyond the railsand rail-to-rail output that swings within 50mV of therails. Single or dual supplies as low as +1.8V ( ± 0.9V)and up to +5.5V ( ± 2.75V) may be used. They areopTImized for low-voltage, single-supply operation.The OPA333 family offers excellent CMRR withoutthe crossover associated with traditionalcomplementary input stages. This design results insuperior performance for driving analog-to-digitalconverters (ADCs) without degradation of differentiallinearity.The OPA333 (single version) is available in theSC70-5, SOT23-5, and SO-8 packages. TheOPA2333 (dual version) is offered in DFN-8 (3mm ×3mm), MSOP-8, and SO-8 packages. All versionsare specified for operation from – 40 ° C to +125 ° C.
