EVAL-ADM2495EEBZ

EVAL-ADM2495EEBZ is a board that allows simplified, efficient evaluation of the ADM2495E 5.7kVRMS, 250kbps half-duplex signal isolated RS-485 transceiver. The EVAL-ADM2495EEBZ can also be used to evaluate the higher speed 20Mbps ADM2495E-1 by replacing the low-speed part with the higher speed part. The EVAL-ADM2495EEBZ comes with options for the evaluation of the ADM2495E/ADM2495E-1 device in an individual system. Digital and RS-485 bus signals are easily accessible via the screw terminal blocks on the EVAL-ADM2495EEBZ. Each digital input can be configured via the on-board jumper options. Two on-board ADP7104 low dropout (LDO) regulators accept an input voltage of up to 20V and output a range of selectable supply voltages to the VDD1 and VDD2 pins, configurable via jumper options. The LDO regulators can be bypassed to power the ADM2495E/ADM2495E-1 VDD1 and VDD2 supply pins directly from external power supplies.
