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. 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 1μA. The single version is available in the MicroSIZE SOT23-5 (SOT23-6 for shutdown) and SO-8. The dual version is available in MSOP-8, MSOP-10, and SO-8 packages. Quad packages are available in TSSOP-14 and SO-14 packages. All versions are specified for operation from –40°C to +125°C.
