The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 are micropower, 4-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal oxide semiconductor (CMOS) and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler devices. As shown in Figure 3 in the data sheet, in standard operating mode, when ENx = 0 (internal refresh enabled), the current per channel is less than 10 μA. When ENx = 1 (internal refresh disabled), the current per channel drops to less than 1 μA.

The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 family of quad 2.5 kV digital isolation devices are packaged in a small 16-lead QSOP and 20-lead SSOP, freeing almost 70% of board space compared to isolators packages in wide body SOIC packages.

The devices withstand high isolation voltages and meet regulatory requirements, such as UL and CSA standards. In addition to the space savings, the ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 operate with supplies as low as 2.25 V.

Despite the low power consumption, all models of the ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 provide low, pulse width distortion at <8 ns. In addition, every model has an input glitch filter to protect against extraneous noise disturbances.

APPLICATIONS

  • General-purpose, low power multichannel isolation
  • 1 MHz, low power peripheral interface (SPI)
  • 4 mA to 20 mA loop process controls

Product Detail

The EVAL-ADuM144x-EBZ supports the ADuM144x family of ultra low power, quad channel isolators. It provides a JEDEC standard QSOP16 pad layout, support for signal distribution, loop back, bypass capacitors and loads referenced to VDDX or GNDX. Signal sources can be wired onto the board as well as brought in through Edge mounted SMA connectors (not provided) or terminal blocks for power connections. The board includes 200 mil header positions for compatibility with Tektronix active probes.

The board follows best PCB design practices for four layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation practices are included in this board.
