ADM211EARU Interface - Drivers, Receivers, Transceivers Application Field and Working PrincipleThe ADM211EARU is an integrated low-voltage CMOS line driver and receiver designed for RS-232 applications. It is designed to provide reliable serial communication over standard DB9 and RJ11 cables. The ADM211EARU is a versatile and power efficient integrated driver and receiver that offers a wide range of solutions to meet a variety of communication interface needs.The ADM211EARU is designed to fit a wide range of applications. It is ideal for use in portable and handheld devices (cellular phones, PDAs, and other portable consumer electronics), PCMCIA, PC cards, and embedded communication systems. With its low-power consumption and in-rush current protection, the device can be used in handheld and portable products.The ADM211EARU is a complete design solution for interfacing between RS-232 UARTs or other serial communication standards and logic circuits. The device integrates the necessary line driver and receiver functions into a single 8-lead SOIC package. It features low-power consumption, 2KV ESD protection, in-rush current protection, and a wide power supply range.The ADM211EARU contains two line drivers (one for each of the receiver and transmitter outputs), two receivers, and a drivers\' enable output. The ADM also includes a separate driver enable output that allows the receiver to be disabled while the drivers are still enabled. This feature eliminates cross talk between the transmitter and receiver when one side is inactive.The ADM211EARU integrates a receiver and a driver in the same package. This eliminates the need for an external driver, and reduces the overall power consumption of the RS-232 interface. The device operates with a single 3V to 5.5V power supply rail and can detect high, low, and mid-level logic levels. The receiver has a hysteresis input voltage range of ±250mV, and its output levels are compatible with both 3V and 5V logic systems. The driver is capable of driving up to 500mA in either direction.The ADM211EARU features an integrated 2KV ESD protection circuit that protects the device from damage due to electrostatic discharge. It also includes an in-rush current limiting circuit to prevent current spikes on power-up. The device is RoHS compliant and is available in a small 8-pin SOIC package.The ADM211EARU is a reliable and power efficient solution for serial communication needs. Its integrated line driver and receiver make it an ideal solution for portable and embedded applications. With its low-power consumption and small package size, the device can be used in many different applications.
