DESCRIPTION

The AO1378 amplifier is a new generation of zero-drift, micro-power, CMOS operational amplifiers, the AO1378 offer bandwidth of 1.8MHz, rail-to-rail inputs and outputs, and single-supply operation from 1.8V to 5.5V. The Combination of low input voltage noise, high gain bandwidth (1.8MHz) and low power (180μA) enable AO1378 to achieve optimum performance for low-power precision applications.

The AO1378 uses chopper stabilized technique to provide very low offset voltage (less than 5μV maximum) and near zero drift over temperature. Low quiescent supply current of 180μA per amplifier and very low input bias current of 20pA make the devices an ideal choice for low offset, low power consumption and high impedance applications. The AO1378 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 AO1378 is available in SOT-25 and SOP8 packages.
