About Isolated Amplifier/ADC

Our isolated amplifier/ADC integrates precision isolated amplifier and isolated modulator, optimized for shunt resistor-based current sensing or other small signal measurement applications including industrial control, industrial power supply, frequency inverters, automotive driver etc. areas.

The CA-IS1200/1300 devices are high-precision isolated amplifiers and optimized for shunt-resistor-based current sensing. 

The CA-IS1204/1305/1306 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.
