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.
