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.
