Description

Demonstration circuit 1791A is a serial peripheral interfacebus (SPI) or inter-IC bus (I2C) μModule isolator with dualadjustable 5V regulators featuring the LTM®2887. The democircuit features an EMI optimized circuit configuration andprinted circuit board layout. All components are integratedinto the μModule isolator. The demo circuit operatesfrom a single external supply on VCC. The part generates output voltages on VCC2 and VL2 which may be adjustedby external programming resistors. It communicates allnecessary signaling across the isolation barrier throughLTC’s isolator μModule technology.
