Analog Devices Inc. EVAL-ADM2763EEBZ Evaluation Board
Analog Devices Inc. EVAL-ADM2763EEBZ Evaluation Board allows for the simplified, efficient evaluation of the ADM2763E RS-485 Transceiver. Digital and RS-485 bus signals are easily accessible via the screw terminal blocks on the EVAL-ADM2763EEBZ. Each digital input can be configured via the onboard jumper options. Two onboard ADP7104 low dropout (LDO) regulators accept an input voltage up to 20V and output a range of selectable supply voltages to the VDD1 pin and VDD2 pin, which are configurable via jumper options. The LDO regulators can be bypassed to power the ADM2763E VDD1 supply pin and VDD2 supply pin directly from an external power supply.
