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 the MicroSize 5-pin SOT-23 (6-pin SOT-23 for shutdown) and 8-pin SOIC. The dual version is available in 8-pin VSSOP, 10-pin VSSOP, 16-pin UQFN, and 8-pin SOIC packages. Quad packages are available in 14-pin TSSOP and 14-pin SOIC packages. All versions are specified for operation from –40°C to +125°C.
