Product Details

The EVAL-ADM2895EEBZ allows simplified, efficient evaluation of the ADM2895E/ADM2895E-1, 5.7kVRMS, 250kbps (for ADM2895E) half-duplex signal and power isolated RS-485 transceiver. The EVAL-ADM2895EEBZ can also be used to evaluate the higher speed 20Mbps (for ADM2895E-1) by replacing the low-speed part with the higher speed part.

The ADM2895E/ADM2895E-1 features an integrated, isolated, DC-to- DC converter that provides power to the isolated side of the device with no additional ICs required.

The EVAL-ADM2895EEBZ comes with options for the evaluation of the ADM2895E/ADM2895E-1 device in an individual system. Digital and RS-485 bus signals are easily accessible by the screw terminal blocks on the EVAL-ADM2895EEBZ. Each digital input can be configured by the on-board jumper options.

An on-board ADP7104 low dropout (LDO) regulator accepts an input voltage of up to 20V and outputs a range of selectable supply voltages to the VCC pin, configurable by jumper options. The LDO regulator can be bypassed to power the ADM2895E/ADM2895E-1 VCC supply pin directly from an external power supply.
