The OPA363 and OPA364 families are high-performance CMOS operational amplifiers optimized for very low voltage, single-supply operation. These miniature, low-cost amplifiers are designed to operate on single supplies from 1.8V (0.9V) to 5.5V (2.75V). Applications include sensor amplification and signal conditioning in battery-powered systems. The OPA363 and OPA364 families offer excellent CMRR without the crossover associated with traditional complimentary input stages. This results in excellent performance for driving Analog-to-Digital (A/D) converters without degradation of differential linearity and THD. The input commonmode range includes both the negative and positive supplies. The output voltage swing is within 10mV of the rails.
