The ADM232LJR-REEL is a low-power, two-channel serial receiver IC. It has a wide receiver differential input range from 0.2V to 15V, and it is compatible with standard levels such as TTL and CMOS. The device consists of two independent receivers featuring state-of-the-art pulse-width and hysteresis together with a Very Low Offset, low noise, and low jitter. The ADM232LJR-REEL is well suited for interfacing with Fast Ethernet, EIA-232, and other serial data transmission applications.

Applications

The ADM232LJR-REEL is ideal for applications such as level translation, signal conditioning, and signal restoration. It is designed to interface with Fast Ethernet and many other serial data transmission applications that require low power consumption and low noise levels. An example is its use in point-of-sale systems and cash register applications, which require controlled data transfer. The device is also suited for data acquisition and environmental monitoring applications such as transmission and distribution equipment, alarm monitoring systems, and radio transceivers.

Working Principle

The ADM232LJR-REEL consists of two independent receivers, each with its own plated-through holes for connection to a signal source. Both receivers feature differential inputs which accept input from a single signal source, allowing for signal-conditioning and voltage-level conversion. The signal is first converted from its single signal source to a differential signal through the differential inputs. The signal is then amplified by a pair of amplifiers, one for each channel, increasing the signal’s voltage-level. The amplified signal is then sent to the output buffer, which converts the signal to a single-ended signal, suitable for transmission over communication networks. The output buffer also reduces the signal jitter and impedance level, increasing the signal’s noise immunity.

The ADM232LJR-REEL also features an off-state quiescent power dissipation of 8-µA, making it ideal for energy-sensitive applications. Furthermore, the device includes shutdown logic, allowing it to be powered down when not in use, further decreasing the power consumption of the application.

Conclusion

The ADM232LJR-REEL is an excellent choice for applications which require low-power and noise-free signal conditioning and level translation. Its wide receiver differential input range from 0.2V to 15V makes it suitable for a variety of applications, such as cash registers and point-of-sale systems. The device also features low levels of power consumption, allowing for longer battery life in portable applications. Furthermore, the off-state quiescent power dissipation of 8-µA and the shutdown logic make the ADM232LJR-REEL a good choice for energy-sensitive applications.
