EVALUATION KIT CONTENTS
EVAL-ADM2795EEBZ
GENERAL DESCRIPTION
Use the EVAL-ADM2795EEBZ to easily evaluate the ADM2795E
5 kV rms signal isolated RS-485/RS-422 transceiver with
Level 4 IEC EMC and 24 V supply fault protection. The EVAL-
ADM2795EEBZ evaluation board is easily configured through
jumper connections and screw terminal blocks for signal and
power connections. The EVAL-ADM2795EEBZ can be powered
with either a 9 V battery or a standard configurable bench top
power supply. An on-board trimmer potentiometer and an on-
board regulator circuit on both VDD1 and VDD2 allow easy
power configuration when connected to a 9 V battery.
CERTIFIED IEC EMC RS-485 EVALUATION BOARD
The EVAL-ADM2795EEBZ evaluation board has been lab tested
and certified to provide RS-485 A, B bus pin protection against
IEC 61000-4-5 surges to ±4 kV, IEC 61000-4-4 EFT to ±2 kV,
and IEC 61000-4-2 ESD to ±8 kV for contact and ±15 kV for air.
The ADM2795E isolation barrier was also tested and certified to
provide robust IEC EMC immunity. The EVAL-ADM2795EEBZ
can withstand high voltage faults to ±42 V ac/dc peak on RS-485
A, B bus pins. The EVAL-ADM2795EEBZ meets stringent EMI
emissions targets with a 6 dB μV margin from EN 55022 Class B
limits, by using a 120 pF, 0603 body size capacitor on the printed
circuit board (PCB) trace connected to the RxD pin.
