1.8V, MICRO-POWER CMOS ZERO-DRIFT OPERATIONAL AMPLIFIERS

DESCRIPTION

The dual UTC ULV2333 CMOS operational amplifiers provide

very low offset voltage and zero-drift over time and temperature.

The miniature, high precision, low quiescent current amplifiers

offer high-impedance inputs that have a wide input common mode

range of 100mV beyond the rails and rail-to-rail output that swings

within 35mV of the rails. Single or dual supplies as low as 1.8V

(±0.9V) and up to 5.5V (±2.75V) may be used. They are optimized

for low voltage, single or dual supply operation.

The UTC ULV2333 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.
