The ADuM2250 / ADuM2251 are hot swappable digital isolators with nontlatching, bidirectional communication channels and are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with stand-alone optocouplers.

The ADuM2250 provides two bidirectional channels, supporting a complete isolated I2C interface. The ADuM2251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required.

The ADuM2250 / ADuM2251 contain hot swap circuitry to prevent data glitches when an unpowered card is inserted onto an active bus.

These isolators are based on iCoupler® chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size, and power consumption advantages compared to optocouplers. The ADuM2250 / ADuM2251 integrate iCoupler channels with semiconductor circuitry to enable a complete, isolated I2C interface provided in a small form factor package.

APPLICATIONS

  • Isolated I2C, SMbus, or PMBus Interfaces
  • Multilevel I2C interfaces
  • Power supplies
  • Networking
  • Power over Ethernet

ADuM1250 Evaluation Board

  • Provisions for cable terminations
  • Support for PCB edge mounted coaxial connectors
  • Easy configuration

Product Detail

The EVAL-ADuM1250EBZ supports two bidirectional channels for evaluation of isolated I2C interfaces in 8-lead SOIC packages. The evaluation board provides a JEDEC standard, 8-lead SOIC_N pad layout. This layout supports signal distribution, loopback, and loads referenced to the VDDx or GNDx planes, as well as optimal bypass capacitance. Signal sources can be conducted to the board through header pins or through edge mounted Sub- miniature Version A (SMA) connectors (SMA connectors must be ordered separately).

Screw terminal blocks on the evaluation board provide power connections. The board includes 200 mil (5.08 mm) header positions for compatibility with active probes (probe header pins must be ordered separately). The EVAL-ADuM1250EBZ evaluation board can be used to evaluate the ADuM1250, ADuM1251, ADuM2250, and ADuM2251 devices. Although the pad layout on the EVAL- ADuM1250EBZ does not support the ADuM2250 and ADuM2251 16-lead SOIC_W and SOIC_IC packages, these devices are functionally equivalent to the ADuM1250 and ADuM1251, respectively, for the purposes of evaluation. They differ only by package and isolation capabilities. Therefore, evaluations of the ADuM1250 and ADuM1251 can be applied to the ADuM2250 and ADuM2251 as well.

The evaluation board follows best printed circuit board (PCB) design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other electromagnetic interference (EMI) or noise mitigation design features are included on this evaluation board. For high speed operation, or when ultralow emissions are required, refer to the AN-1109 Application Note for additional evaluation board layout techniques.

Full specifications for the ADuM1250 are available in the ADuM1250 data sheet, which must be consulted in conjunction with User Guide UG-1100 when working with the evaluation board.
