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 1.8 V (±0.9 V) to 5.5 V(±2.75 V). 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 feature results in excellent performance for driving analog-to-digital (A/D) converters without degradation of differential linearity and THD. The input common-mode range includes both the negative and positive supplies. The output voltage swing is within 10 mV of the rails. The OPA363 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is less than 1 µA. The single version is available in theMicroSize 5-pin SOT-23 (6-pin SOT-23 for shutdown) and 8-pin SOIC.
