GENERAL DESCRIPTION
The ADM2482E/ADM2487E are isolated data transceivers with
±15 kV ESD protection and are suitable for high speed, halfduplex or full-duplex communication on multipoint transmission
lines. For half-duplex operation, the transmitter outputs and
receiver inputs share the same transmission line. Transmitter
Output Pin Y is linked externally to Receiver Input Pin A, and
Transmitter Output Pin Z to Receiver Input Pin B. The parts are
designed for balanced transmission lines and comply with
TIA/EIA-485-A-98 and ISO 8482:1987(E).
The devices employ the Analog Devices, Inc., iCoupler®
technology to combine a 3-channel isolator, a three-state
differential line driver, and a differential input receiver into a
single package. An on-chip oscillator outputs a pair of square
waveforms that drive an external transformer to provide isolated
power. The logic side of the device is powered with either a 5 V
or a 3.3 V supply, and the bus side is powered with an isolated
3.3 V supply.
The ADM2482E/ADM2487E driver has an active high enable,
and the receiver has an active low enable. The driver output
enters a high impedance state when the driver enable signal
is low. The receiver output enters a high impedance state when
the receiver enable signal is high.
The device has current-limiting and thermal shutdown features
to protect against output short circuits and situations where bus
contention might cause excessive power dissipation. The part is
fully specified over the industrial temperature range of −40°C to
+85°C and is available in a 16-lead, wide-body SOIC package.

The ADM2482E/ADM2487E contain thermal shutdown
circuitry that protects the parts from excessive power dissipation during fault conditions. Shorting the driver outputs to a
low impedance source can result in high driver currents. The
thermal sensing circuitry detects the increase in die temperature
under this condition and disables the driver outputs. This
circuitry is designed to disable the driver outputs when a die
temperature of 150°C is reached. As the device cools, the drivers
are re-enabled at a temperature of 140°C.
Given the geometry of the receiving coil and an imposed
requirement that the induced voltage is, at most, 50% of the
0.5 V margin at the decoder, a maximum allowable magnetic
field can be determined using Figure 31.

With combinations of strong magnetic field and high frequency,
any loops formed by PCB traces can induce error voltages large
enough to trigger the thresholds of succeeding circuitry.
Care should be taken in the layout of such traces to avoid this
possibility.

APPLICATIONS INFORMATION
PRINTED CIRCUIT BOARD LAYOUT
ISOLATED POWER SUPPLY CIRCUIT
The isolated RS-485 transceiver of the ADM2482E/ADM2487E
requires no external interface circuitry for the logic interfaces.
Power supply bypassing is required at the input and output supply
pins (see Figure 33).
The ADM2482E/ADM2487E integrate a transformer driver
that, when used with an external transformer and linear voltage
regulator (LDO), generates an isolated 3.3 V power supply to be
supplied between VDD2 and GND2, as shown in Figure 34.
Bypass capacitors are most conveniently connected between
Pin 3 and Pin 4 for VDD1 and between Pin 15 and Pin 16 for
VDD2. The capacitor value must be between 0.01 μF and 0.1 μF.
The total lead length between both ends of the capacitor and
the input power supply pin must not exceed 20 mm.
Pin D1 and Pin D2 of the ADM2482E/ADM2487E drive a
center-tapped Transformer T1. A pair of Schottky diodes and a
smoothing capacitor are used to create a rectified signal from the
secondary winding. The ADP3330 LDO provides a regulated
3.3 V power supply to the ADM2482E/ADM2487E bus side
circuitry (VDD2).
Bypassing Pin 9 and Pin 16 is also recommended unless the
ground pair on each package side is connected close to the
package.

If the ADM2482E/ADM2487E are powered by 5 V on the logic
side, then a step-down transformer should be used. For optimum
efficiency, the transformer turns ratio should be chosen to ensure
just enough headroom for the ADP3330 LDO to output a regulated
3.3 V output under all operating conditions.

Figure 33. Recommended Printed Circuit Board Layout
In applications involving high common-mode transients, care
must be taken to ensure that board coupling across the isolation
barrier is minimized. Furthermore, the board layout must be
designed such that any coupling that does occur equally affects
all pins on a given component side.

Failure to ensure this can cause voltage differentials between
pins exceeding the absolute maximum ratings of the device,
thereby leading to latch-up or permanent damage.
The transformer primarily used with the ADM2482E/ADM2487E
must be a center-tapped transformer winding. The turns ratio
of the transformer must be set to provide the minimum required
output voltage at the maximum anticipated load with the minimum input voltage. Table 13 shows ADM2482E/ADM2487E

When the ADM2482E/ADM2487E are powered by 3.3 V on the
logic side, a step-up transformer is required to compensate for
the forward voltage drop of the Schottky diodes and the voltage
drop across the regulator. The transformer turns ratio should be
chosen to ensure just enough headroom for the ADP3330 LDO
to output a regulated 3.3 V output under all operating conditions.
ADM2482E/ADM2487E
line must be terminated at the receiving end in its characteristic
impedance, and stub lengths off the main line must be kept as
short as possible. For a half-duplex operation, this means that
both ends of the line must be terminated, because either end can
be the receiving end.
TYPICAL APPLICATIONS
Figure 35 and Figure 36 show typical applications of the
ADM2482E/ADM2487E in half-duplex and full-duplex
RS-485 network configurations. Up to 256 transceivers can
be connected to the RS-485 bus. To minimize reflections, the
