Replacement verdict
Compatible functional replacement candidate
The ADM3056EBRIZ-RL is a viable functional replacement candidate for the ADM3052BRWZ in isolated CAN applications, sharing the same isolated CAN transceiver function and SOIC-16 wide-body footprint, though the designer must validate supply voltage range, data rate, and isolation rating against the target design requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3052BRWZ | ADM3056EBRIZ-RL | Why it matters |
|---|---|---|---|
| Data Rate | 1 Mbps | 12 Mbps | Determines the maximum bus speed the transceiver can support; a higher data rate enables faster CAN communication but may require tighter timing and layout considerations. |
| Isolation Voltage (VISO) | 5 kV rms | 5 kV rms | Specifies the galvanic isolation rating between the bus side and logic side, critical for safety and ground-loop breaking in industrial networks. |
| Integrated Isolated DC-DC | Yes (isoPower) | No | An integrated isolated power supply eliminates the need for an external isolated DC-DC converter, reducing board space and BOM count; its absence requires external isolation power. |
| Supply Voltage (VCC) | 5 V | 5 V | Defines the logic-side supply rail; matching values allow drop-in compatibility with the same system power architecture. |
| Package / Pin Count | 20-Lead SOIC_W | 16-Lead SOIC_W | Different package footprints and pin counts mean the parts are not drop-in replacements and require PCB layout changes. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +125°C | A wider temperature range supports harsher industrial environments and provides greater thermal margin in demanding applications. |
| Number of Channels | 1 Tx / 1 Rx | 1 Tx / 1 Rx | Confirms both are single-channel CAN transceivers, so the basic communication topology is compatible. |
| Protocol Support | CAN (ISO 11898) | CAN FD (ISO 11898-2) | CAN FD support allows higher payloads and faster data phases; a classic CAN-only device cannot interoperate at FD speeds. |
| Common-Mode Voltage Range | -7 V to +12 V | -7 V to +12 V | Defines the bus common-mode tolerance; matching ranges ensure equivalent robustness against ground potential differences. |

Frequently asked questions
What are the primary functional differences between the ADM3052BRWZ and the ADM3056EBRIZ-RL?
The ADM3052BRWZ is a 5 kV rms isolated, CAN transceiver with an integrated isolated DC-to-DC converter that provides a fully isolated CAN interface in a single package. The ADM3056EBRIZ-RL is a 5 kV rms signal-isolated CAN FD transceiver without an integrated isolated power supply, requiring an external isolated DC-to-DC converter for the bus-side supply. Both are manufactured by Analog Devices.
Do the ADM3052BRWZ and ADM3056EBRIZ-RL support CAN FD data rates?
The ADM3056EBRIZ-RL is specified for CAN FD operation with data rates up to 12 Mbps. The ADM3052BRWZ is specified for classic CAN operation at data rates up to 1 Mbps and is not rated for CAN FD data rates.
Are the ADM3052BRWZ and ADM3056EBRIZ-RL pin-to-pin or package compatible?
No. The ADM3052BRWZ is offered in a 16-lead SOIC_W package, while the ADM3056EBRIZ-RL is offered in a 16-lead SOIC_W package with a different pin function assignment due to the absence of the integrated isolated power converter. The two devices are not direct drop-in replacements and require separate PCB layouts.
What isolation rating do both devices provide?
Both the ADM3052BRWZ and the ADM3056EBRIZ-RL provide 5 kV rms isolation per UL 1577 and are rated for 1 kV rms working voltage per VDE 0884-10 (VDE 0884-11 for the ADM3056E). Designers should confirm the specific certification level required by the end application against the respective datasheets.
Does the ADM3056EBRIZ-RL require an external isolated power supply?
Yes. The ADM3056EBRIZ-RL provides signal isolation only and requires an external isolated DC-to-DC converter to supply the isolated bus-side VDD2 rail. The ADM3052BRWZ integrates an isolated DC-to-DC converter, so no external isolated supply is needed for the bus side.
What are the supply voltage requirements for each device?
The ADM3052BRWZ operates from a single 5 V supply on the logic side and generates the isolated bus-side supply internally. The ADM3056EBRIZ-RL operates with a logic-side supply of 1.7 V to 5.5 V and requires an external isolated supply of 4.5 V to 5.5 V on the bus side. Refer to the respective datasheets for exact limits.
Which device is better suited for space-constrained isolated CAN designs?
The ADM3052BRWZ is generally preferred for space-constrained designs because its integrated isolated DC-to-DC converter eliminates the need for an external isolated power supply and associated components. The ADM3056EBRIZ-RL requires additional board area for an external isolated converter but offers CAN FD capability and a wider logic-side supply range.
Are both devices rated for the same operating temperature range?
Both the ADM3052BRWZ and the ADM3056EBRIZ-RL are specified for the industrial temperature range of −40 °C to +85 °C. Designers should verify the exact temperature grade against the ordering code and datasheet for the specific application.
