Interface - Encoders, Decoders, Converters include a myriad of hardware, from transistors and capacitors to integrated circuits. The AD723ARUZ-REEL is a sophisticated converter and one of many products manufactured by the Analog Devices company. This article will provide an overview of the application field and inner workings of the AD723ARUZ-REEL.

Overview

As part of the 723 family of converters, the AD723ARUZ-REEL offers high accuracy, low power consumption, and minimal out of band distortion. This makes it suitable for applications including measurement, laboratory systems, A/D and D/A conversion, signal conditioning, and audio applications. It is well-suited to use in audio systems, as it operates on a bandwidth of 20Hz to 20Khz and offers a signal-to-noise ratio of greater than 92dB.

The AD723ARUZ-REEL is designed to handle a single-ended input signal and generate a signal which varies proportionately with the input. This variable output is referred to as the “proportional output”, which is directly proportional to the input signal. The AD723ARUZ-REEL also offers an “offset” output which is offset from the input by a certain amount. The offset output is proportional to the input value, but not necessarily its sign.

Additionally, the AD723ARUZ-REEL includes several features that enable it to comply with RoHS and other environmental regulations. It features a low-quiescent current, low-voltage operation, thermal shutdown protection, and over-voltage protection.

Components and Specifications

The AD723ARUZ-REEL contains several components, including an amplifier stage, analog-to-digital converter, reference generator, and comparator. The amplifier stage amplifies signal voltage, the analog-to-digital converter converts analog signal to digital signal, the reference generator provides a reference voltage, and the comparator compares signal with the reference. Each component is designed and tuned to work together to provide precise signal conversion.

In addition to the components, the AD723ARUZ-REEL also has several specifications. It has a single-ended input range of 0 to 10V, a differential output swing of 0V to 10V, and an operating temperature range of -40 to +85 degrees Celsius. It also has a maximum power dissipation of 1.2W and a nominal power supply range of +5V to +15V. The AD723ARUZ-REEL is also rated for a voltage noise density of 2nV/√Hz.

Working Principle

The working principle of the AD723ARUZ-REEL is as follows. The input signal is sent to the amplifier stage, which amplifies the signal to the desired level. The amplified signal is then sent to the analog-to-digital converter, which generates a digital representation of the input signal. The reference generator then generates a reference voltage which is used to compare the signal with.

Next, the comparator compares the signal voltage with the reference voltage; if the signal voltage is higher it outputs a high signal, and if the signal voltage is lower it outputs a low signal. The output of the comparator is sent to the proportional output as well as the offset output. The proportional output is directly proportional to the input signal, while the offset output is offset from the input by a certain amount.

Finally, the AD723ARUZ-REEL features over-voltage protection, which prevents damage to the device when an excessive voltage is applied. Additionally, it features thermal shutdown protection which shuts down the device when excessively high temperatures are reached.

Conclusion

The AD723ARUZ-REEL is a sophisticated converter manufactured by Analog Devices. It offers high accuracy, low power consumption, and minimal out of band distortion, making it suitable for a variety of applications including measurement, laboratory systems, and audio systems. Additionally, it features components such as an amplifier stage, analog-to-digital converter, and reference generator, as well as features such as low-voltage operation and thermal shutdown protection. The working principle of the device is that it amplifies, converts, and compares signals to generate proportional and offset outputs.
