HCPL-7860 Datasheet (Avago) - Optically Isolated Sigma-Delta (S-D) Modulator

HCPL-7860, Optically Isolated Sigma-Delta (S-D) Modulator

The HCPL-7860/HCPL-786J Optically Isolated Modulator and HCPL-0872 Digital Interface IC or digital filter together form an isolated programmable two-chip analog-to-digital converter.

The isolated modulator allows direct measurement of motor phase currents in power inverters.

In operation, the HCPL-7
