Description

The INA745x is a digital power monitor with an

integrated current sensing element along with a 16-

bit delta-sigma ADC specifically designed for current-

sensing applications. The device can measure full-

scale currents up to ±39.32A with common-mode

voltage support from –0.1V to +40V.

The INA745x reports current, bus voltage, die

temperature, power, energy and charge accumulation

while employing a precision ±0.5% integrated

oscillator, all while performing the needed calculations

in the background. The integrated temperature sensor

is ±2.5°C accurate over the junction temperature

range.

The low offset and gain drift design of the INA745x

allows the device to be used in precise systems that

do not undergo multi-temperature calibration during

manufacturing.

The device allows for 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.
