The ADM1490E / ADM1491E are RS-485/RS-422 transceivers with ±8 kV ESD protection and are suitable for high speed, full-duplex communication on multipoint transmission lines. In particular, the ADM1490E/ADM1491E are designed for use in motor control applications requiring communications at data rates up to 16 Mbps.The ADM1490E / ADM1491E are designed for balanced transmission lines and comply with TIA/EIA-485-A-98. The devices each have a 12 kΩ receiver input impedance for unit load RS-485 operation, allowing up to 32 nodes on the bus.The differential transmitter outputs and receiver inputs feature electrostatic discharge circuitry that provides protection to ±8 kV using the human body model (HBM).The ADM1490E / ADM1491E operate from a single 5 V power supply. Excessive power dissipation caused by bus contention or output shorting is prevented by short-circuit protection and thermal circuitry. Short-circuit protection circuits limit the maximum output current to ±250 mA during fault conditions. A thermal shutdown circuit senses if the die temperature rises above 150°C and forces the driver outputs into a high impedance state under this condition.The receiver of the ADM1490E / ADM1491E contains a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating).The ADM1490E / ADM1491E feature extremely fast and closely matched switching times. Minimal driver propagation delays permit transmission at data rates up to 16 Mbps, and low skew minimizes EMI interference.The ADM1490E/ADM1491E are fully specified over the commercial and industrial temperature ranges. The ADM1490E is available in two packages: a narrow body, 8-lead SOIC and an 8-lead MSOP. The ADM1491E is also available in two packages: a narrow body, 14-lead SOIC and a 10-lead MSOP.APPLICATIONS RS-485/RS-422 interfaces Industrial field networks High data rate motor control Multipoint data transmission systems Single-ended-to-differential signal conversion

The ADM3053 is an isolated controller area network (CAN) physical layer transceiver with an integrated isolated dc-to-dc converter. The ADM3053 complies with the ISO 11898 standard.The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator, a CAN transceiver, and Analog Devices isoPower® dc-to-dc converter into a single SOIC surface mount package. An on-chip oscillator outputs a pair of square waveforms that drive an internal transformer to provide isolated power. The device is powered by a single 5 V supply realizing a fully isolated CAN solution.The ADM3053 creates a fully isolated interface between the CAN protocol controller and the physical layer bus. It is capable of running at data rates of up to 1 Mbps.The device has current limiting and thermal shutdown features to protect against output short circuits. The part is fully specified over the industrial temperature range and is available in a 20-lead, wide-body SOIC package.The ADM3053 contains isoPower technology that uses high frequency switching elements to transfer power through the transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards.
