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
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.
