Test Equipment

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.
