Amplifiers

Power MonitorCurrent SenseSPI16-bit ADC

The INA239 is a high-precision 16-bit digital power monitor with an SPI interface, ideal for high-side and low-side current sensing up to 85V.

Best for

  • High-side current sensing
  • Precision power monitoring
  • Industrial and telecom applications

Avoid if

  • Low-voltage applications requiring extreme power efficiency (though it has a shutdown mode)

Check before use

  • Ensure the shunt resistor is sized correctly for the expected current and ADC range.
