dc1790a-d DC1790A-D LTM2886-5I Demo Board | I2C μModule Isolator (5.0V Supply) Demonstration circuit 1790A is a serial peripheral interface bus (SPI) or inter-IC bus (I2C) μModule? isolator with fixed ±5V and adjustable 5V regulated power featuring the LTM2886. 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, ?which may be adjusted by an external programming resistor, and fixed voltages on V+ and V–. It communicates all necessary signaling across the isolation barrier through LTC’s isolator μModule technology. DC1790A-D
