The INA700 is a digital power monitor with an integrated shunt resistor along with a 16-bit delta-sigma ADC specifically designed for current sensing applications. The device can measure full-scale currents up to ±15.728A, over the common-mode voltage range of –0.3V to +40V.

The INA700 reports current, bus voltage, die temperature, power, energy and charge accumulation with a precision ±0.5% integrated oscillator, all while performing the needed calculations in the background. The integrated temperature sensor is ±3°C accurate over the junction temperature range.

The low offset and gain error drift of the INA700 allows use in systems that do not undergo temperature calibration during manufacturing.

The device features selectable ADC conversion times from 50µs to 4.12ms as well as sample averaging from 1x to 1024x, which further helps reduce the noise of the measured data and allows for optimization of overcurrent detection windows.

The device is available in a tiny PowerWCSP (DSBGA) package to minimize the solution size and maximize thermal performance.
