ADM2490E:  5 kV Signal Isolated, High Speed (16 Mbps), ESD Protected, Full Duplex RS-485 Transceiver

Информация о продукте

Статус продукта:Производство

The ADM2490E is an isolated data transceiver with ±8 kV ESD protection that is suitable for high speed, full-duplex communi-cation on multipoint transmission lines. It is designed for balanced transmission lines and complies with ANSI TIA/EIA-485-A-1998 and ISO 8482: 1987(E). The device employs Analog Devices, Inc., iCoupler® technology to combine a 2-channel isolator, a three-state differential line driver, and a differential input receiver into a single package.

The differential transmitter outputs and receiver inputs feature electrostatic discharge circuitry that provides protection to ±8 kV using the human body model (HBM). The logic side of the device can be powered with either a 5 V or a 3 V supply, whereas the bus side requires an isolated 5 V supply.

The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where bus contention could cause excessive power dissipation.

The ADM2490E is available in a wide body, 16-lead SOIC package and operates over the −40°C to +105°C temperature range.

Solving Isolation Challenges in Power Conversion Applications
This webcast will present solutions to isolation challenges in power conversion applications. Among the topics to be discussed are the limitations of traditional methods of isolation (such as utilization of optocouplers and pulse transformers) vs. more efficient and cost effective solutions that utilize digital isolators. If you are currently using optocouplers and pulse transformers, this is a webcast you should attend.
