CA-IS1204W Datasheet (Chipanalog) - Isolated Sigma-Delta Modulator

CA-IS1204W, Isolated Sigma-Delta Modulator

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 modul
