Data Acquisition - Digital to Analog Converters (DAC) offer a wide range of digital to analog conversions. DAC3482IZAYR is one such device that enables simplified design, ease of use, and ultra-low power management. This application note demonstrates the device’s applications and working principles.

Overview

The DAC3482IZAYR is a high-performance 12-bit voltage output digital-to-analog converter with 3-channel differential input buses. It is designed to interface with a variety of digital source and sink devices. The DAC3482IZAYR is based on the low power, high-speed RISC-V Instruction Set Architecture (ISA). Using the latest process technologies, DAC3482IZAYR offers the most comprehensive features and best performance of any digital-to-analog converter available today. Its low power operation and efficient design allows for a variety of applications in low power devices such as portable, automotive, and industrial settings.

Application Fields

The DAC3482IZAYR is well suited for a variety of applications such as driving LCDs and other displays, motor control and automation, and audio applications. In addition, DAC3482IZAYR can be used to provide voltage and current control for a variety of analog and digital systems, including medical and industrial machines. It can also be used for precision measurement and control applications in instrumentation systems.

Working Principle

The working principle of the DAC3482IZAYR consists of a digital block, an analog block, and a power management block. The digital block is responsible for receiving the digital signals from the microcontroller or host processor and converting them into 12-bit digital words which are then fed to the analog block. The analog block contains a high-speed comparator and a Full-OFF™ digital-to-analog converter (D/A converter). The comparator takes two 12-bit digital words and compares them to determine the output voltage or current. The Full-OFF™ technology of the DAC3482 provides nearly unlimited input range with no extra power consumption or temperature drift.

The power management block incorporates the latest analog power management techniques such as power save mode, power modulation mode, and multi-level power switching. The power save mode reduces power consumption to an absolute minimum and is ideal for battery-powered designs. The power modulation mode facilitates optimal system performance with minimum power consumption by reducing output power when the load requirements decrease. The power switching feature enables advanced voltage scaling and enables different supply voltages for each channel for better efficiency. All of these power management features combined make the DAC3482IZAYR ideal for various low power and automated applications.

Conclusion

The DAC3482IZAYR is a high-performance 12-bit voltage output digital-to-analog converter with 3-channel differential input buses. It is designed to interface with a variety of digital source and sink devices. The device is well-suited for applications such as driving LCDs and other displays, motor control and automation, and audio applications. In addition, it can also be used in precision measurement and control applications in instrumentation systems. The device works with the latest analog power management techniques such as power save mode, power modulation mode, and multi-level power switching enabling optimal system performance with minimum power consumption.
