OPA333

1.8V、17µA、微功耗、高精度、零漂移 CMOS 运算放大器

The OPAx333 series of CMOS operational amplifiers use a proprietary auto-calibration technique to simultaneously provide very low offset voltage 10 µV, maximum and near-zero drift over time and temperature. These miniature, high-precision, low quiescent current amplifiers offer high-impedance inputs that have a common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 50 mV of the rails. Single or dual supplies as low as 1.8 V ±0.9 V and up to 5.5 V ±2.75 V can be used. These devices are optimized for low-voltage, single-supply operation.

The OPAx333 family offers excellent CMRR without the crossover associated with traditional complementary input stages. This design results in superior performance for driving analog-to-digital converters ADCs without degradation of differential linearity.

The single version is available in the 5-pin SOT-23, SOT, and 8-pin SOIC packages, while the OPA2333 dual version is available in the 8-pin VSON, SOIC, and VSSOP packages. All versions are specified for operation from –40°C to 125°C.
