Avago Technologies HCPL786J
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. This modulation provides for high noise margins and excellent immunity against isolation-mode transients.| Part No. | HCPL786J |

DESCRIPTION
In operation, the HCPL-7860/HCPL-786J Isolated Modulator converts a low-bandwidth analog input into a highspeed one-bit data stream by means of a Sigma-Delta (Σ−∆) over-sampling modulator. The modulator data and onchip sampling clock are encoded and transmitted across the isolation boundary where they are recovered and decoded into separate high-speed clock and data channels.FEATURES
