Functional Overview
The ADM3053BRWZ-REEL7 integrates two critical functions for isolated CAN nodes: a high-speed CAN transceiver and a galvanic isolation barrier. The iCoupler-based isolation carries digital signals (e.g., TXD to RXD) across chip-scale transformers instead of LEDs and photodiodes, enabling long-life, low-power isolation without optocoupler aging effects. On the power side, Analog Devices’ isoPower technology creates an isolated 5 V domain from the primary 5 V input, supplying the CAN-side transceiver and any limited additional circuitry within the power budget specified in the datasheet.
By combining data and power isolation in a single IC, the ADM3053BRWZ-REEL7 minimizes BOM count, lowers leakage paths that can complicate compliance, and simplifies PCB layout compared to discrete isolation-plus-transceiver approaches. This level of integration is particularly valuable in multi-node distributed systems, where dozens or hundreds of identical isolated CAN nodes must be produced reliably and cost-effectively.
CAN transceiver behavior
The device supports up to 1 Mbps, matching the requirement for most classic high-speed CAN networks used in industrial controls. It provides the standard differential bus interface with CANH and CANL lines, translating logic-level TXD/RXD signals on the microcontroller side into robust physical signaling on the bus. Because the power to the isolated side is generated internally, the CAN bus interface can remain galvanically isolated from the local controller even when only a single 5 V rail is available on the primary side.
Power domains and grounding
The ADM3053BRWZ-REEL7 operates from 5 V on the logic side and generates an isolated 5 V on the CAN side via isoPower. Designers should implement segregated ground planes for primary and secondary domains, and follow the datasheet’s layout practices to achieve the intended isolation integrity and EMI performance. Proper decoupling at the primary supply and at the isolated output is essential to meet transient load demands and to control switching noise from the internal converter.
Packaging, Handling, and Assembly
- Package: SOIC-20W (wide-body)
- Mounting: Surface Mount
- Pin count: 20
- Packaging: Tape & Reel (REEL7)
The wide-body SOIC format aids creepage and clearance distances inherent to isolation designs, making it a common footprint in safety-critical and industrial systems. Delivered on tape-and-reel, the ADM3053BRWZ-REEL7 is well-suited to automated placement. Standard SMT practices apply; observe moisture sensitivity handling as recommended by Analog Devices and reflow profiles consistent with lead-free assembly. For final assembly, keep high di/dt loops tight on both primary and secondary sides and separate noisy power-switching paths from sensitive analog or clock lines.
Applications
- Industrial CAN networks
- Factory and process automation
- Building automation and HVAC
- Distributed control systems
The single-chip combination of isolated power and data link enables compact, repeatable node designs. It is particularly helpful when retrofitting isolation into systems that previously relied on nonisolated transceivers or discrete isolated power modules.
Design-In Tips
- Layout for isolation integrity and EMI: Follow the datasheet’s recommended PCB layout for isoPower-based devices. Maintain clear separation between primary and secondary planes and route switching nodes carefully to contain emissions.
- Decoupling and bulk capacitance: Place local decoupling close to supply pins on both sides of the barrier, and ensure adequate bulk capacitance for the isolated rail generated by isoPower as described in the datasheet.
- Thermal considerations: The integrated DC/DC converter dissipates power. Provide adequate copper for heat spreading and verify thermal performance under worst-case loading.
- Bus protection and termination: Implement proper CAN termination (typically at both ends of the bus) and protection elements appropriate to the installation environment. Specific ESD/transient ratings are not provided here; consult the datasheet if you require explicit limits.
- System power budgeting: Although isoPower supplies the isolated domain, total available current on the secondary side is limited. Budget for transceiver consumption and any additional circuitry powered from the isolated rail per the datasheet.

Comparison Considerations for Replacements
If you are evaluating replacements or alternates for the Analog Devices ADM3053BRWZ-REEL7, verify the following criteria:
