DAC8728SPAG

Data Acquisition - Digital to Analog Converters (DAC) are devices used to convert digital signals into analog signals. The DAC8728SPAG is a specific type of DAC that is used in a wide range of applications. This article will provide an overview of the DAC8728SPAG, exploring its application fields and working principles.

Overview

The DAC8728SPAG is an 8-bit, voltage-output digital-to-analog converter (DAC) from Intersil Corporation. Its purpose is to convert digital data from a controller or other computer system into analog data in the form of a voltage or current. The DAC8728SPAG features on-chip buffered voltage outputs, allowing it to drive up to 100 mA into a load. It has an operating voltage of +5 V, and a one-microsecond update time. It is offered in a 32-pin plastic dual-in-line package or an SOIC package.

Application Fields

The versatile nature of the DAC8728SPAG makes it suitable for use in a number of industries and applications. It is often used in the medical industry because of its accuracy, fast response, and low power consumption. It is also used in industrial settings where precise control over voltage or current is required. The DAC8728SPAG is used in military and aerospace applications, where its reliable and rugged design makes it suitable for use in harsh environments. Additionally, it is used in consumer electronics such as TVs, audio systems, and gaming consoles.

Working Principles

The DAC8728SPAG utilizes a resistive voltage ladder for converting the digital data it receives into the analog voltage or current output. When data is received, the DAC8728SPAG determines the relative position of each bit in the digital data and sends multiple currents from different sections of the voltage ladder. Based on the relative position of the bits and the current levels from the ladder, an analog voltage or current is generated at the output of the device. The accuracy and resolution of the conversion is determined by the number of bits received and the resolution of the voltage ladder.

Conclusion

The DAC8728SPAG is a versatile and reliable digital-to-analog converter with a wide range of applications. Its ability to convert digital data into accurate analog voltage or current makes it suitable for use in medical, industrial, military, and consumer electronics industries. Its working principle of using a resistive voltage ladder to convert digital data into analog signals also makes it an ideal choice for precision control of voltage/current levels.
