ADM202EAN Application Field and Working Principle

The ADM202EAN is a high performance, low power, dual EIA-232 transceiver integrated circuit. As a device designed for high speed communication, it provides a bridge between logic level inputs and the EIA-232 levels for output.

Application Field

The ADM202EAN is used in a variety of application fields, from consumer electronics such as printers and scanners, to industrial control applications, the ADM202EAN is a popular choice for low speed data transmission. The device supports a variety of different data rates from 9.6 Kbps up to 1 Mbps and offers integrated ESD protection for both the input and output lines which makes it ideal for automated industrial applications. The ADM202EAN also offers adjustable receiver hysteresis and low driver output on-state resistance to minimize EMI and improve signal integrity, enabling designers to take advantage of the increased data rates available.

Working Principle

The ADM202EAN has two independent transceivers which enable full-duplex communication. The transceivers incorporate ESD protection circuits which enable robust signal communication over long distances. In addition, the device also offers adjustable receiver hysteresis and low driver output on-state resistance to minimize EMI and improve signal integrity, enabling designers to take advantage of the increased data rates available.The device is implemented using a sophisticated level-shifting technique that allows the signal to switch between EIA-232 and logic level signals without the need for an external level translator. This allows the device to operate at both nominal signal levels and at any level between them. The device also features an automatic power-down feature that reduces power consumption when no data is being transferred.

Conclusion

The ADM202EAN is a robust, low power consuming device that is ideally suited for the dual EIA-232 transceiver, offering a variety of data rate options up to 1 Mbps and providing integrated ESD protection for both the input and output lines. The device also offers adjustable receiver hysteresis and low driver output on-state resistance to minimize EMI and improve signal integrity. The ADM202EAN can be used in a variety of applications from consumer to industrial, and is an excellent choice for low speed data transmission.
