Replacement verdict
Compatible functional replacement candidate
The ADM3055EBRIZ and ADM3052BRWZ are both isolated CAN transceivers from Analog Devices with matching 5 Mbps data rates and 5 V supply rails, making the ADM3055EBRIZ a viable functional upgrade candidate for the ADM3052BRWZ in isolated CAN bus designs. However, the ADM3055EBRIZ integrates an isoPower isolated DC-DC converter that eliminates the need for an external isolated supply required by the ADM3052BRWZ, and the two devices differ in package footprint and isolation rating, so layout, power architecture, and safety certification must be revalidated before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3055EBRIZ | ADM3052BRWZ | Why it matters |
|---|---|---|---|
| Data Rate | 12 Mbps | 1 Mbps | Maximum CAN bus throughput; a faster transceiver supports higher-bandwidth networks and shorter bus latency. |
| Isolation Rating | 5 kV rms (galvanic isolation) | 5 kV rms (galvanic isolation) | Determines the safe voltage barrier between the bus side and logic side; both meet the same 5 kV rms isolation class. |
| Integrated DC-DC Converter | Yes (isoPower integrated isolated power) | No (requires external isolated supply) | An integrated isolated DC-DC simplifies design, reduces board space, and eliminates an external isolated power module. |
| Supply Voltage (VCC) | 5 V single supply | 5 V (VCC) with separate VDD2 bus-side supply | Affects power architecture; the ADM3055E runs from a single 5 V rail while the ADM3052 needs a separate bus-side supply. |
| Package | 20-lead SOIC_W (wide body) | 16-lead SOIC_W (wide body) | Footprint and pin count differ, so the parts are not drop-in PCB replacements for one another. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +85°C | Wider temperature range supports harsher industrial environments and higher ambient operating margins. |
| Number of Channels / Direction | 1 Tx / 1 Rx (CAN transceiver) | 1 Tx / 1 Rx (CAN transceiver) | Both provide a single bidirectional CAN channel, so functional signaling topology is equivalent. |
| Bus Fault Protection | ±40 V bus fault protection | ±40 V bus fault protection | Protects the transceiver against overvoltage faults on the CAN bus in industrial wiring environments. |
| Common-Mode Voltage Range | -7 V to +12 V | -7 V to +12 V | Defines tolerance to ground potential differences between nodes; identical range means equivalent bus robustness. |
| Standards Compliance | ISO 11898 CAN, UL 1577, CSA, VDE | ISO 11898 CAN, UL 1577, CSA, VDE | Certification to CAN and isolation safety standards confirms interoperability and regulatory acceptance. |

Frequently asked questions
What are the key differences between the ADM3055EBRIZ and ADM3052BRWZ?
The ADM3055EBRIZ is a 5 kV rms isolated CAN FD transceiver with an integrated isolated DC-to-DC converter, supporting data rates up to 12 Mbps, housed in a 20-lead SOIC_W package. The ADM3052BRWZ is a 5 kV rms isolated CAN transceiver without an integrated isolated power supply, supporting data rates up to 1 Mbps, housed in a 16-lead SOIC_W package. The ADM3055E integrates isolated power, while the ADM3052 requires an external isolated supply.
Are the ADM3055EBRIZ and ADM3052BRWZ pin-to-pin compatible?
No. The ADM3055EBRIZ uses a 20-lead SOIC_W package, while the ADM3052BRWZ uses a 16-lead SOIC_W package. The different pin counts and pin functions prevent direct pin-to-pin substitution; the PCB land pattern must be redesigned.
Do both devices support CAN FD?
Only the ADM3055EBRIZ supports CAN FD, with data rates up to 12 Mbps. The ADM3052BRWZ is specified for classic CAN operation up to 1 Mbps and is not rated for CAN FD data rates.
Does the ADM3052BRWZ require an external isolated power supply?
Yes. The ADM3052BRWZ does not include an integrated isolated DC-to-DC converter, so an external isolated power supply is required for the isolated side. The ADM3055EBRIZ integrates an isolated DC-to-DC converter, eliminating the need for a separate isolated supply.
What is the isolation rating of each device?
Both the ADM3055EBRIZ and ADM3052BRWZ are rated for 5 kV rms isolation, suitable for galvanically isolated CAN bus applications.
Can the ADM3055EBRIZ be used as a drop-in replacement for the ADM3052BRWZ?
No. Beyond the package and pin count differences, the ADM3055EBRIZ integrates isolated power and supports CAN FD up to 12 Mbps, whereas the ADM3052BRWZ requires external isolated power and supports up to 1 Mbps. A redesign of the PCB and power architecture is required.
Which device is better suited for space-constrained designs requiring isolated power?
The ADM3055EBRIZ is better suited because it integrates the isolated DC-to-DC converter, reducing external component count and board space compared with the ADM3052BRWZ, which requires an external isolated supply.
