Demonstration circuit 1791A is a serial peripheral interface bus (SPI) or inter-IC bus (I2C) μModule isolator with dual adjustable 5V regulators featuring the LTM2887. The demo circuit features an EMI optimized circuit configuration and printed circuit board layout. All components are integrated into the μModule isolator. The demo circuit operates from a single external supply on VCC. The part generates output voltages on VCC2 and VL2 which may be adjusted by external programming resistors. It communicates all necessary signaling across the isolation barrier through LTC’s isolator μModule technology.
