Evaluating the ADM3251E
FEATURES
GENERAL DESCRIPTION
2.5 kV fully isolated (power and data) RS-232 transceiver
Convenient connections for power and signal through screw
terminal blocks
5 V operation
Easily configurable through jumper connections
Test points for measuring all signals
All external components required for correct operation
Patchwork area supports through hole devices
The simple, 2-layer ADM3251E evaluation board can be used
for easy evaluation of the ADM3251E RS-232 transceiver with
isolated power and signal. Screw terminal blocks provide convenient connections for the power and signal connections. Test
points are included on the power and signal lines on both sides
of the isolation barrier.
