CA-IS1200U Overview
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.
