CAN bus transceiver for 2 Mbps industrial links
The MAX3057ASA+ is a full-duplex CAN transceiver from Analog Devices, handling one driver and one receiver in a single 8-SOIC package. It supports the CANbus protocol at data rates up to 2 Mbps, making it a fit for high-speed industrial control networks where standard 500 kbps CAN is too slow. The 150 mV receiver hysteresis cleans up noisy bus signals — the difference between a clean frame and a CRC error on a long stub.
Supply voltage and temperature grade
If your MCU runs at 3.3V, you need a separate 5V rail or a level-shifted CAN controller; the MAX3057ASA+ does not include a 3.3V-compatible VIO pin. The -40°C to 125°C operating range covers the full automotive Grade 1 temperature band. At 125°C junction, the driver's output drive capability derates, but the receiver still meets the CAN recessive/dominant thresholds per ISO 11898-2.
The 1.27 mm pitch is layout-friendly on two-layer boards — no via-in-pad required for the SOIC-8 body. Supplied in tube packaging, this is a prototyping-friendly quantity. For production volumes, the tape-and-reel variant (MAX3057ASA+T) is the usual pick for pick-and-place lines.
