Description
General part information
INA745B Series
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 ±39.32 A with common-mode voltage support from –0.1 V to +40 V.
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.
