3 Description
The INA741 is a digital power monitor with an
integrated current sensing element along with a 20-
bit delta-sigma ADC specifically designed for currentsensing
applications. The device can measure fullscale
currents up to ±39.32 A with common-mode
voltage support from –0.1 V to +85 V.
The INA741 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 INA741
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.
