Aperçu du produit

DC1503A-B demonstration board is for evaluating LTM2881 a complete isolated RS485/RS422 uModule transceiver + power. A single supply powers both sides of the interface through an integrated, isolated, low noise, efficient output DC/DC converter. Coupled inductors and an isolation power transformer provide isolation between the line transceiver and the logic interface. This device is ideal for systems where the ground loop is broken allowing for large common mode voltage variation. Uninterrupted communication is guaranteed for common mode transients. Maximum data rates are 20Mbps or 250Kbps in slew limited mode. Transmit data, DI and receive data, RO, are implemented with event driven low jitter processing. The receiver has a one eighth unit load supporting up to 256 nodes per bus.
  • High common mode transient immunity
  • 5V Operation
  • Integrated selectable 120ohm termination
  • High input impedance failsafe RS485 receiver
  • Current limited drivers and thermal shutdown
  • Compatible with TIA/EIA-485-A and PROFIBUS
  • High impedance output during internal fault condition
  • Low current shutdown mode
  • General purpose CMOS isolated channel
  • No external components required
