Description
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.
In operation, the HCPL-7860/
HCPL-786J 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.
A 0.1 μF bypass capacitor must be connected between pins V
DD
and Ground
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation, which may be induced by ESD.
