Analog Devices Inc. EVAL-ADM2461EEBZ Evaluation Board
Analog Devices Inc. EVAL-ADM2461EEBZ Evaluation Board allows for the simplified, efficient evaluation of the ADM2461E Signal Isolated RS-485 Transceiver. Digital and RS-485 bus signals are easily accessible via the screw terminal blocks on the EVAL-ADM2461EEBZ. 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 ADM2461E VDD1 supply pin and VDD2 supply pin directly from an external power supply.
The Analog Devices Inc. EVAL-ADM2461EEBZ Evaluation Board includes a footprint for the ADM2461E isolated, half-duplex RS-485 transceiver in a 10.10mm x 10.65mm, 16-lead, standard small outline, wide body (SOIC_W) package.
