Key Features

  • 100 dB minimum CMRR (118 dB typical) for accurate differential current sensing in noisy environments
  • Ultra-low input offset voltage of 50 µV for precision measurements
  • Wide common-mode voltage range up to 36 V supporting high-side and low-side sensing
  • Voltage-feedback operational amplifier architecture with built-in frequency compensation
  • Compact MSOP-8 (S-PDSO-G8) package for space-constrained PCB designs

Applications

The INA301A2IDGKT is widely used in industrial motor control systems for precise phase-current monitoring and overcurrent protection. It is also deployed in battery management systems and DC power supplies where accurate high-side current sensing at voltages up to 36 V is critical. Additional applications include smart metering, solar inverters, and server power monitoring where low offset and high CMRR ensure measurement integrity.
