CIRCUIT DESCRIPTION
ELECTRICAL ISOLATION
In the ADM2483, electrical isolation is implemented on the
logic side of the interface. Therefore, the part has two main
sections: a digital isolation section and a transceiver section (see
Figure 26). Driver input and data enable signals, applied to the
TxD and DE pins, respectively, and referenced to logic ground
(GND1), are coupled across an isolation barrier to appear at the
transceiver section referenced to isolated ground (GND2).
Similarly, the receiver output, referenced to isolated ground in
the transceiver section, is coupled across the isolation barrier to
appear at the RxD pin referenced to logic ground.
iCoupler Technology
The digital signals are transmitted across the isolation barrier
using iCoupler technology. This technique uses chip-scale
transformer windings to couple the digital signals magnetically
from one side of the barrier to the other. Digital inputs are
encoded into waveforms that are capable of exciting the
primary transformer winding. At the secondary winding, the
induced waveforms are then decoded into the binary value that
was originally transmitted.
