ADM3251EARWZ Description
The ADM3251EARWZ is a high-speed, 2.5 kV fully isolated, single-channel RS-232/V.28 transceiver device that operates from a single 5 V power supply. Due to the high ESD protection on the RIN and TOUT pins, the device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged and unplugged. The ADM3251EARWZ incorporates dual-channel digital isolators with isoPower™ integrated, isolated power. There is no requirement to use a separate isolated dc-to-dc converter.
ADM3251EARWZ Features
2.5 kV fully isolated (power and data) RS-232 transceiver
isoPower integrated, isolated dc-to-dc converter
460 kbps data rate
1 Tx and 1 Rx
Meets EIA/TIA-232E specifications
0.1 μF charge pump capacitors
High common-mode transient immunity: >25 kV/μs
Operating temperature range: −40°C to +85°C
Wide body, 20-lead SOIC package
ADM3251EARWZ Applications
High-noise data communications
Industrial communications
General-purpose RS232 data links
Industrial/telecommunications diagnostic ports
