The Optically Isolated Modulator A7860/HCPL-7860/HCPL-786J. In power inverters, this isolated modulator enables for direct measurement of motor phase currents. The modulator output is transferred across the isolation barrier via the drivers. 

The A7860/HCPL-7860/HCPL-786J Isolated Modulator (optocoupler with 3750 VRMS dielectric withstand voltage rating) uses a SigmaDelta () over-sampling modulator to convert a low-bandwidth analogue input into a high-speed one-bit data stream. High noise margins and strong immunity to isolation-mode transients are provided by this modulation. The on-chip sampling clock and modulator data are encoded and transferred beyond the isolation border, where they are recovered and decoded into independent high-speed clock and data channels.


  • Linearity of 12 bits 
  • Effective Resolution: 12-bit with a 5-second signal delay (14-bit with a 102-second signal delay) (with HCPL-0872)
  • Over-Range Detection in 3 seconds (with HCPL-0872)
  • 200 mV Input Range with a Single 5 V Supply 
  • Internal Reference Voltage Matching of 1% 
  • Offset Calibration (with HCPL-0872)
  • Operating Temperature Range: -40°C to +85°C
  • Isolation Transient Immunity at 15 kV/s
  • UL 1577, CSA, and IEC/EN/DIN EN 60747-5-2 safety approvals


  • Motor Phase and Rail Current Sensing
  • Data Acquisition Systems
  • Industrial Process Control
  • Inverter Current Sensing
  • General Purpose Current Sensing and Monitoring
