The CA-IS1300x 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-IS1300x devices utilize silicon oxide (SiO₂) isolation  barriers and support up to 5-kV_RMS 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-IS1300x 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 highside supply voltage detection functions contribute to fault  diagnostics and system safety.

The CA-IS1300x series provide two input voltage range  options and the smaller rank (±50 mV) allows significant  reduction of the power dissipation through the shunt  resistor.
