VSON (DEK)-15-See data sheet
The INA780x 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 ±78.64 A with common-mode voltage support from –0.1 V to +85 V.
The INA780x 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 INA780x 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 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.
