Agilent HCPL-7560 Optically Isolated Sigma-Delta (Σ-∆) Modulator
Data Sheet
Features • 8-bit Linearity Description The HCPL-7560 Optically Isolated Modulator and HCPL0872 Digital Interface IC or digital filter together form an isolated programmable twochip analog-to-digital converter.
The isolated modulator allows direct measurement of motor phase currents in power inverters.
In operation, the HCPL-7560 Isolated Modulator (optocoupler with 3750 VRMS dielectric withstand
voltage rating) converts a lowbandwidth analog 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 excel...
