The NA226 senses current over a common-mode bus voltage range of 0V to 36V, independent of supply voltage. The device monitors the shunt voltage drop and bus supply voltage. Programmable calibration values, conversion times and averaging functions combined with an internal multiplier allow direct reading of current (in amps) and power (in watts).
