HCPL-7860-000E

The HCPL-7860 Isolated modulator converts a low bandwidth analog input into a high-speed one-bit data stream by means of a Sigma-Delta over sampling modulator. This modulation provides 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. The HCPL-7860 when used in conjunction with the HCPL-0872 digital interface IC or digital filter together forms an isolated programmable two-chip analog-to-digital converter. This modulator allows direct measurement of motor phase currents in power inverters.
