DESCRIPTION/ORDERING INFORMATION
The OPA333 series of CMOS operational amplifiers uses a proprietary auto-calibration technique to
simultaneously provide very low offset voltage (10 mV max) and near-zero drift over time and temperature. These
miniature, high-precision, low-quiescent-current amplifiers offer high-impedance inputs that have a
common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 50 mV of the rails. Single
or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V) may be used. They are optimized for
low-voltage single-supply operation.
The OPA333 family offers excellent common-mode rejection ratio (CMRR) without the crossover associated with
traditional complementary input stages. This design results in superior performance for driving analog-to-digital
converters (ADCs) without degradation of differential linearity.
The OPA333 (single version) is available in the SOT23-5 package.
