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.
