Analog Devices Inc. ADM33051E High-Speed CAN FD Transceiver
Analog Devices ADM33051E High-Speed CAN FD Transceiver is a robust high-speed, low-power CAN transceiver operating with a 3.3V supply. The ADM33051E features ±60V overvoltage fault protection on the data transmission lines during all modes of operation, including power-down. The 2Mbps maximum data rate supports high-speed protocols based on the CAN physical layer, including Flexible Data Rate (CAN FD). Enhanced ESD protection allows the device to withstand up to ±20kV HBM on the transceiver interface pins without latch-up or damage.
An extended ±25V input common-mode range and high common-mode rejection in the CAN receiver provide additional tolerance to large ground-loop voltages. The Analog Devices ADM33051E is a sophisticated CAN driver with active symmetry control that maintains tight control of the common-mode voltage for excellent electromagnetic emissions, and includes variable slew-rate and split termination support for improved EME reduction.
