描述： The HCPL-7860-300E is a 1-channel 8-pin surface-mount optically isolated Sigma-Delta (S-D) Modulator allows direct measurement of motor phase currents in power inverters. In operation, the isolated modulator (optocoupler with 3750VRMS dielectric withstand voltage rating) converts a low bandwidth analogue input into a high-speed one-bit data stream by means of a Sigma-Delta (Σ-?) over-sampling modulator. This modulation provides for high noise margins and excellent immunity against isolation-mode transients. The modulator data and on-chip sampling clock are encoded and transmitted across the isolation boundary where they are recovered and decoded into separate high-speed clock and data channels. .
