DC1748A-A

DC1748A-A is a demo board for LTM2883 SPI/digital μModule isolator with adjustable ±12.5V and 5V regulated power. 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 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, 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.
