Key Features

  • Dual-channel zero-drift architecture eliminates input offset voltage drift over time and temperature
  • Ultra-low supply current of 17µA per channel enables battery-powered and energy-harvesting designs
  • Wide supply voltage range from 1.8V to 5.5V suits portable and single-cell applications
  • High CMRR of 130dB (typ) / 106dB (min) ensures accurate signal measurement in noisy environments
  • Rail-to-rail input and output maximizes dynamic range at low supply voltages

Applications

The OPA2333AIDGKT is well-suited for precision sensor signal conditioning in medical instrumentation, portable industrial test equipment, and wearable devices where ultra-low power and accuracy are critical. Its zero-drift topology makes it ideal for thermocouple and bridge amplifier circuits requiring stable DC accuracy over temperature. The dual-channel configuration in a compact MSOP-10 package is also commonly used in low-power data acquisition front-ends and precision current-sensing circuits.
