Description
The HCPL-7560 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-7560
Isolated Modulator
(optocoupler with 3750 V
RMS
dielectric withstand voltage
rating) converts a low-
bandwidth 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
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.
