Product Overview
NCID9311 is an industrial galvanically isolated high speed 3 channel digital isolator with output enabled. This device supports isolated communications thereby allowing digital signals to communicate between systems without conducting ground loops or hazardous voltages. This is patented galvanic off-chip capacitor isolation technology and optimized IC design to achieve high insulation and high noise immunity, characterized by high common mode rejection and power supply rejection specifications. The thick ceramic substrate yields capacitors with ~25 times the thickness of thin film on−chip capacitors and coreless transformers. Typical application includes isolated PWM control, industrial fieldbus communications, microprocessor system interface, programmable logic control, isolated data acquisition system, and voltage level translator.
