3 Description
The OPA2333 series of CMOS operational amplifiers
uses a proprietary auto-calibration technique to
simultaneously provide very low offset voltage and
near-zero drift over time and temperature(1). 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 150 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 OPA2333 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.
