OPA2333P (ACTIVE) Industry's smallest, low-power, high-precision dual Op Amp with >300kHz GBW

 

Description

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, single-supply operation.

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.
