Product Details

The EVAL-ADM3053EBZ allows for the simple evaluation of the ADM3053 signal and power isolated controller area network (CAN) transceivers. The evaluation board allows all of the input and output functions to be exercised without the need for external components.

The EVAL-ADM3053EBZ device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator, a CAN transceiver, and an Analog Devices isoPower® dc-to-dc converter into a single small outline IC (SOIC) surface-mount package. An on-chip oscillator outputs a pair of square waveforms that drive an internal transformer to provide isolated power. The device is powered by a single 5 V supply, realizing a fully isolated CAN solution.

The ADM3053 contains isoPower technology that uses high frequency switching elements to transfer power through the transformer. For layout guidelines, see the AN-0971 Application Note.

For full details, see the ADM3053 data sheet, which must be used in conjunction with UG-234 when using the evaluation board.
