OPA364

1.8V、高 CMR、RRIO 运算放大器

The OPA363 and 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 _Micro_Size 5-pin SOT23 6-pin SOT23 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.
