The OPA2364 and OPA4364 are high-performance CMOS operational amplifiers optimized for 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 OPAx364 family offers 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 total harmonic distortion (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 dual version is available in an SO-8 package and the quad package is available in an
SO-14 package. All versions are specified for operation from –40°C to 125°C.
