Product Details:

ADM3252E是一款高速、2.5 kV 完全隔离、双通道 RS-232/V.28 transceiver，采用3.3 V或5 V单电源供电。由于RIN1、RIN2、TOUT1和 TOUT2 引脚提供高压ESD保护，因此ADM3252E非常适合在恶劣的电气环境中工作，或频繁插拔RS-232电缆的场合。

Utilizing isoPower's™ integrated isolation power supply, ADM3252E provides four independent isolation channels. There is no need to use a separate isolated DC-DC converter. The device uses Analog Devices' chip-scale transformer iCoupler® technology to isolate logic signals from integrated DC-DC converters. As a result, the device provides a completely isolated solution.

The isoPower™ technology in ADM3252E utilizes high-frequency switching elements to transmit power through their transformers. Particular care should be taken when designing printed circuit board (PCB) layouts and must comply with relevant radiation standards. For more information on board layout considerations, refer to Application Note AN-0971: "Radiation Control Recommendations for isoPower Devices".

ADM3252E compliant with EIA/TIA-232E and ITU-T V.28 specifications and has data rates up to 460 kbps. The doubled/negative voltage converter uses four 0.1 μF external charge pump capacitors, which allows the device to be powered from a single 3.3 V or 5 V supply. ADM3252E is available in a 44-pin, chip-scale ball grid array (CSP_BGA) package and is rated for an operating temperature range of −40°C to +85°C.
