CA-IS1204W Overview
The CA‐IS1204 device is series of precision isolated sigma‐ delta (Σ‐Δ) modulator and optimized for shunt resistor‐ based current sensing or other small signal measurement applications. The input current‐sense amplifier monitors current flow through a shunt (sense) resistor and the sigma‐delta modulator converts the analog input to a digital bit stream of 1's and 0's at a much higher frequency. The digital output...
