General Description
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-VRMS (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.
