DESCRIPTION
Demonstration circuit 1748A is a serial peripheral interface
bus (SPI) or inter-IC bus (I2C) SPI/digital or I2C μModule
isolator with adjustable ±12.5V and 5V regulated power
featuring the LTM2883. The demo circuit features an EMI
optimized circuit confi guration 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,
V+, and V–, which may be adjusted by external programming
resistors. It communicates all necessary signaling
across the isolation barrier through LTC’s isolator μModule
technology.
