The ADuM340E/ADuM341E/ADuM342E are quad-channel digital isolators based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and back-to-back monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and meet CISPR 32/EN 55032 Class B limits at 5 Mbps. The maximum propagation delay is 10 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 ADuM340E/ADuM341E/ADuM342E data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.7 kV rms (see Figure 26 in the data sheet). The devices operate with the supply voltage on either side ranging from 2.25 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.

Two different fail-safe options are available, by which the outputs transition to a predetermined state when the input power supply is not applied.

APPLICATIONS

  • Serial peripheral interface (SPI) data converter isolation
  • RS-485 and controller area network with flexible data rate (CAN FD) industrial field bus isolation
  • PWM controller signal isolation
  • General-purpose multichannel isolation

  • U4 not inserted to allow evaluation of other supported iCoupler digital isolator in 16-lead SOIC_W package
  • Enable controls
  • Small, easy configuration optimized for rapid evaluation on breadboards/prototype boards
  • Test points can be fitted to measure all signals

Product Details

The EVAL-ADuM34XEEBZ evaluation board supports simplified, efficient evaluation of the 5.7 kV rms ADuM340E/ADuM341E/ADuM342E family of iCoupler® digital isolators. The EVAL-ADuM34XEEBZ board also grants the ability to examine multiple other 16-lead SOIC_W iCoupler digital isolators via the unpopulated U4, which provides the user a JEDEC standard 16-Lead SOIC_W pad layout and routing appropriate for the evaluation of supported devices.

The EVAL-ADuM34XEEBZ board features V shaped grooves between each component (U1 to U4) that allow the user to split the PCB into sections and examine a specific device of their choice on a breadboard or similar prototyping board for ease of use. If U4 is populated with a different supported device, refer to the appropriate device data sheet.

Power and the inputs/outputs can be connected either directly to the pin header connectors or onto a prototyping board.

Enable controls are provided via the pin headers, which can be configured via a digital input, or the user can refer to the schematic in Figure 2 in the user guide and populate the pull-up resistors on the VE1/VE2 pins. The pull-ups on the VEx pins are not inserted by default. The 100 kΩ value in the schematic may need to be changed depending on the application needs.

The EVAL-ADuM34XEEBZ board follows printed circuit board (PCB) design practices, including a ground plane on each side of the isolation barrier. No other electromagnetic interference (EMI) or noise mitigation design features are included on this board.

Full specifications for the device under test (DUT) are available in the corresponding ADuM340E/ADuM341E/ADuM342E data sheet, which must be consulted in conjunction with the user guide when using the evaluation board.
