Product Details

The EVAL-ADM2565EEBZ allow the simplified, efficient evaluation of the 3 kV rms ADM2565E signal and power isolated, half-duplex RS-485 transceivers, respectively. The ADM2565E transceivers are available in a small footprint, 10.15 mm × 10.05 mm, 28-lead, small outline, wide body, with fine pitch (SOIC_W_FP) package.

The ADM2565E features an integrated, isolated, dc-to-dc converter that provides power to the isolated side of the device with no additional ICs required.

An on-board ADP7104 low dropout (LDO) regulator accepts an input voltage of 3.3 V to 20 V and regulates the voltage to a selectable 3.3 V or 5 V supply for the V_CC pin of the ADM2565E. The LDO regulator can be bypassed to power the V_CC pin of the ADM2565E directly.

A screw terminal connector on the evaluation boards allows connection to the flexible V_IO logic supply pin of the ADM2565E. This connection allows the ADM2565E to operate with a digital input/output (I/O) voltage from 1.7 V to 5.5 V, which enables communication with nodes using either a 1.8 V or 2.5 V power supply. The V_IO pin can also be supplied from the ADP7104 regulated supply.

Digital and RS-485 bus signals are easily accessible via the screw terminal connectors on each evaluation board. Each digital input can be configured via the on-board jumper options.

Alternative methods can provide the transmit data input (T×D) signal to the ADM2565E. An LTC6900 oscillator is included on each evaluation board and can be optionally configured to provide a clock signal for the T×D digital input within a 1 kHz to 12.5 MHz range. For optimal signal integrity, use the on-board Subminiature Version A (SMA) connector to connect an external data signal at high data rates up to 25 Mbps.

The EVAL-ADM2565EEBZ is populated with the ADM2565E 3 kV rms isolated RS-485 transceiver. The EVAL-ADM2565EEBZ differs from the EVAL-ADM2865EEBZ only by the isolated RS-485 device populated on U3.

For full details on the ADM2565E, see the ADM2565E data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADM2565EEBZ.
