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.

The CA-IS1300x devices are packaged in wide body, 8-pin SOIC packages and specified over the extended industrial temperature range of –40°C to 125°C.
