Oh yes, this is the Microchip device that makes the incorrect claim that no input filtering is needed.
Filtering will often be unavoidable: https://www.planetanalog.com/current-shunt-resistor-inductance-it-matters/
Hello SHH,
As the PAC1934 is a quad digital power monitor, our cross options are pretty limited. Our only multi-channel device of this type is the 3-channel INA3221. Unfortunately the INA3221 does not offer the power accumulator function of the PAC1934, to get that feature you would need the INA233 which is single-channel. Otherwise, you are looking at a more discrete solution with our quad-channel, analog-out INA4180 or INA4181 plus an ADC.
