The ADuM142D1 is a quad-channel digital isolator based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum.

The ADuM142D data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3.0 kV rms or 3.75 kV rms (see the Ordering Guide). The devices operate with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.

Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available, by which the outputs transition to a predetermined state when the input power supply is not applied or the inputs are disabled. The ADuM140E1 / ADuM141E1 / ADuM142E1 is pin-compatible with the ADuM1400 / ADuM1401 / ADuM1402.

APPLICATIONS

  • General-purpose multichannel isolation
  • Serial peripheral interface (SPI)/data converter isolation
  • Industrial field bus isolation

EVAL-3CH4CHEBZ

Universal Evaluation Board for Triple and Quad Channel Standard Digital Isolators in 16-lead SOIC Packages

Universal Evaluation Board for Triple and Quad Channel Standard Digital Isolators in 16-lead SOIC Packages

Features and Benefits

  • Access to all 4 data channels 
  • Enable/disable controls 
  • Multiple connection options 
  • Support for active probes 
  • Provision for cable terminations 
  • Support for PCB edge-mounted coaxial connectors 
  • Easy configuration 
  • Sample iCoupler digital isolator must be ordered separately

Product Detail

The EVAL-3CH4CHSOICEBZ evaluation board supports triple- and quad-channel standard data isolators in 16-lead SOIC packages. The evaluation board provides a JEDEC standard 16-lead SOIC_N and SOIC_W pad layout and routing appropriate for the evaluation of supported devices. The evaluation board provides a connection to power supplies by screw terminals and includes optimal bypass capacitors. Signal channel routing supports signal distribution, loopback, and provides positions for loads referenced to the VDD1/VDD2 and GND1/GND2 planes. Signal sources can be conducted to the board through header pins or edge-mounted SMA connectors; SMA connectors must be ordered separately.

Positions for through-hole 0.2 inch headers compatible with active probes are provided on the printed circuit board (PCB); probe header pins must be ordered separately. The board follows PCB design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation design features are included on the board. In cases of very high speed operation or when ultralow emissions are required, refer to the AN-1109 application note for additional board layout techniques.

Full specifications for the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
