3 Description

The OPA333-Q1 CMOS operational amplifier uses a

proprietary autocalibration technique to

simultaneously provide verylow offset voltage (10 μV

maximum) and near-zero drift over time and

temperature. This miniature, high-precision, lowquiescent-

current amplifier offers 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. The device can use single

or dual supplies as low as 1.8 V (±0.9 V) and up to

5.5 V (±2.75 V), and is optimized for low-voltage

single-supply operation.

The OPA333-Q1 device offers excellent commonmode

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.
