Replacement verdict
Compatible functional replacement candidate
The ADM3050EBRIZ and ADM3052BRWZ are both isolated CAN transceivers from Analog Devices with matching 5 Mbps data rates and 5 kV rms isolation, making them functionally comparable for isolated CAN bus designs. However, they differ in package footprint (SOIC-16 vs SOIC-16 wide body), supply voltage range, and isolated power integration, so board-level validation is required before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3050EBRIZ | ADM3052BRWZ | Why it matters |
|---|---|---|---|
| Data Rate | 12 Mbps | 1 Mbps | Maximum CAN bus data rate supported; higher rates enable faster network communication and shorter bus latency. |
| Isolation Rating | 5 kV rms | 5 kV rms | Galvanic isolation voltage between bus and logic sides; critical for safety and ground-loop immunity in industrial networks. |
| Integrated Isolated DC-DC | Yes (isoPower) | No | An integrated isolated power supply eliminates an external isolated DC-DC converter, reducing board space and BOM cost. |
| Supply Voltage (VCC) | 5 V (single supply) | 5 V (VCC) and 3.3 V/5 V (VIO) | Determines the logic-side and bus-side supply rails required; affects compatibility with host microcontrollers. |
| Package | 20-lead SOIC (wide body) | 16-lead SOIC (wide body) | Footprint and pin count affect PCB layout and whether the parts are drop-in compatible. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +85°C | Wider temperature range supports harsher industrial environments and higher-reliability applications. |
| Number of Channels | 1 Tx / 1 Rx (transceiver) | 1 Tx / 1 Rx (transceiver) | Confirms both are single-channel CAN transceivers suitable for point-to-point and multi-node bus topologies. |
| Common-Mode Voltage Range | -7 V to +12 V | -7 V to +12 V | Bus common-mode tolerance per ISO 11898; ensures reliable communication under ground potential differences. |
| Fail-Safe Receiver | Yes | Yes | Guarantees a defined logic output when the bus is idle or floating, preventing spurious data on the network. |

Frequently asked questions
What are the key differences between the ADM3050EBRIZ and ADM3052BRWZ isolated CAN transceivers?
The ADM3050EBRIZ is a 5 kV rms signal and power isolated CAN FD transceiver with a basic isolation rating, supporting data rates up to 12 Mbps, housed in a 16-lead SOIC wide-body package. The ADM3052BRWZ is a 5 kV rms signal isolated CAN transceiver with an integrated isolated DC-to-DC converter (isoPower) supporting data rates up to 1 Mbps, housed in a 20-lead SOIC wide-body package. The ADM3050EBRIZ supports CAN FD, while the ADM3052BRWZ is limited to classic CAN data rates.
Are the ADM3050EBRIZ and ADM3052BRWZ pin-to-pin or package compatible?
No. The ADM3050EBRIZ uses a 16-lead SOIC wide-body package, while the ADM3052BRWZ uses a 20-lead SOIC wide-body package. The pin counts and pin functions differ, so they are not drop-in replacements and require different PCB land patterns.
Do both devices integrate an isolated DC-to-DC converter for powering the isolated side?
Yes. Both the ADM3050EBRIZ and ADM3052BRWZ integrate Analog Devices isoPower isolated DC-to-DC converters, allowing the isolated CAN bus side to be powered from the logic side without an external isolated supply. This simplifies designs by eliminating a separate isolated power module.
What data rate does each device support?
The ADM3050EBRIZ supports CAN FD data rates up to 12 Mbps, making it suitable for high-bandwidth CAN FD networks. The ADM3052BRWZ supports data rates up to 1 Mbps, which is adequate for classic CAN applications but not for CAN FD.
What is the isolation rating of the ADM3050EBRIZ and ADM3052BRWZ?
Both devices are rated for 5 kV rms isolation. The ADM3050EBRIZ carries a basic isolation rating per UL 1577, while the ADM3052BRWZ is also rated for 5 kV rms isolation. Designers should confirm the specific UL recognition and isolation parameters in the respective datasheets for their safety requirements.
Which device should be selected for a CAN FD network versus a classic CAN network?
For CAN FD networks requiring data rates above 1 Mbps, the ADM3050EBRIZ is the appropriate choice because it supports up to 12 Mbps. For classic CAN networks limited to 1 Mbps, the ADM3052BRWZ is suitable and provides integrated isolated power in a 20-lead package.
Do both devices operate from a single 5 V supply on the logic side?
Yes. Both the ADM3050EBRIZ and ADM3052BRWZ are designed to operate from a 5 V supply on the logic side, with the integrated isoPower converter generating the isolated supply for the CAN bus side. Designers should verify the exact supply voltage range and current requirements in the respective datasheets.
