3 Description

The OPA2333-Q1 CMOS operational amplifiers use a

proprietary autocalibration technique to

simultaneously provide very low offset voltage (10 μV,

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) can be used. This device is

optimized for low-voltage single-supply operation.

The OPA2333-Q1 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 OPA2333-Q1 is specified for operation from

–40°C to +125°C.
