Chipanalog CA-IS1306M25G
The CA‐IS1306x family of devices 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.
