INA238-Q1

The INA238-Q1 is an ultra-precise digital power monitor with 16-bit delta-sigma ADC specifically designed for current-sensing applications. The device can measure a full-scale differential input of ±163.84 mV or ±40.96 mV across a resistive shunt sense element with common-mode voltage support from –0.3 V to +85 V. The low offset and gain drift design of the INA238-Q1 allows it to be used in precise systems that do not undergo multi-temperature calibration during manufacturing. Further, the very low offset voltage and noise allow for use in A to kA sensing applications and provide a wide dynamic range without significant power dissipation losses on the sensing shunt element. The low input bias current of the device permits the use of larger current-sense resistors, thus providing accurate current measurements in the microamp range. The device allows for selectable ADC conversion times from 50 μs to 4.12 ms as well as sample averaging from 1x to 1024x which further helps reduce the noise of the measured data.
