MICRO-POWER , ZERO-DRIFT, RAIL-TO-RAIL INPUT/OUTPUT CMOS OPERATIONAL AMPLIFIERS

DESCRIPTION

The UTC ULV4333 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 ULV4333 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.
