The CA-IS1200 devices are high-precision isolated amplifiers  and optimized for shunt-resistor-based current sensing. Low offset and gain error and drift guarantee that  measuring accuracy is maintained over the entire operating  temperature range.

The CA-IS1200 devices utilize silicon oxide (SiO₂) isolation  barriers and support up to 3750-V_RMS (CA-IS1200U) or 5000- VRMS (CA-IS1200G) galvanic isolation per UL 1577. This  technology separates high- and low-voltage domain to  protect lower-voltage parts from damage and provides low  emissions as well as strong anti-interference capability from  magnetic changes. The high common-mode transient  immunity (CMTI) means that the CA-IS1200 devices  transmit correct signals through isolation barriers and are  suitable for industrial motor controls and drives which  require high-voltage and high-power switching. The internal  input common-mode overvoltage and missing high-side  supply voltage detection functions contribute to fault  diagnostics and system safety.
