The OPA2333P is a CMOS operational amplifier that uses a proprietary auto-calibration
technique to simultaneously provide very low offset voltage (10 µV, maximum) and
near-zero drift over time and temperature. This miniature, high-precision, low quiescent 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. 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,
The OPA2333P also features a specified maximum start-up time. Specified start-up time
ensures high-precision performance after 500 µs of powering the amplifier, allowing for reliable
use in dynamic supply operation.
The OPA2333P offers excellent 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 OPA2333P is available in a 2-mm × 2-mm 8-pin WSON package and is specified for operation from –40°C to 125°C.
