DACs are now widely used in different areas; in fields such as engineering, manufacturing and communications, data acquisition is one of the most popular applications of this technology. The AD5683RBRMZ-3 is an integrated, low cost, low power, industrial-grade dynamic Digital to Analog Converter (DAC) from Texas Instruments. The integrated package of the AD5683RBRMZ-3 is designed to meet several demands: analog performance over temperature, long term stability and long life operation.

The AD5683RBRMZ-3 is targeted for high resolution, low power applications such as process control, motor control, rail-to-rail I/O amplifiers, communication systems, automotive control and sensing systems. It is a 16-bit, code-compatible, single-supply DAC that uses a buffered voltage output structure. The internal registers of the AD5683RBRMZ-3 are configurable and are compatible with a standalone operation mode as well as a part of a master/slave multichannel data acquisition system. The DACs also feature two reference pin pairs that are able to feed a signal that meets the external reference needs of a variety of differential-input signal conditions.

The user-programmable resolutions and simultaneous update operations of the AD5683RBRMZ-3 enable it to be used in a variety of applications. This DAC is designed to offer low power operation (1.5 mW at 3.3 V) while still providing high resolution and precise control over the analog outputs. The output range of the AD5683RBRMZ-3 is software selectable between 0 V and 8 V, in 1 LSB increments. It offers a very accurate performance with high channel linearity and excellent temperature stability.

The working principle of the AD5683RBRMZ-3 is based on a DAC system consisting of two main components: the digital-to-analog converter (DAC) and the voltage output structure. The DAC is the core of the system, which converts a digital word (binary or BCD) into an analog voltage or current. The DAC is connected to a voltage output structure which amplifies, buffers, and translates the output of the DAC into a voltage, current, or other form of analog signal. The voltage output structure includes a switch network, multiple power rails and reference sources and a voltage reference. The switch network is used to digitally control the output of the DAC, while the power rails provide the necessary power to the DAC, voltage reference and voltage output structure.

The AD5683RBRMZ-3 has a simple interface which allows it to be easily integrated into different systems and processes. This DAC is designed to provide the user with a simple and cost effective solution to data acquisition and high resolution conversion, while still providing a reliable, robust and long life operation.
