Introduction

Digital to analog converters (DACs) is essential in our electronic systems for convert digital data to analog signals for further process. The DAC38RF82EVM is a single-channel, ultra-high-resolution digital-to-analog converter (DAC) evaluation module (EVM) designed for industrial automation and sensor measurement applications. It is based on the Texas Instruments’ (TI) DAC38RF82, a wideband, 14-bit, 204MHz sampling rate, Reed-Solomon encoder and error correction digital-to-analog converter (DAC). This device combines an onboard digital-to-analog converter with a built-in power supply to provide a complete solution for frequently used industrial, communications, and automotive applications.

Application Field

The DAC38RF82EVM is ideal for signal condition, gain control, voltage mapping, low latency filtering, gyroscopes, and more. It is an excellent choice for applications in industrial automation, sensor measurement, automotive control, and communications. It is easily adapted to custom applications in the lab or in the field, such as analog-to-digital converter (ADC) performance testing, signal processing, frequency synthesis, data acquisition, digital communications, and pulse-width modulation (PWM) control. The DAC38RF82EVM also has an integrated power supply, which allows the user to get the most out of their applications, while eliminating the need for an additional power supply.

Features

The DAC38RF82EVM includes a wide range of features that make it an excellent choice for digital-to-analog converter applications. The device includes a 204MHz sampling rate, 14-bit resolution, a sigma-delta modulator, a 128-tap digital filter, a built-in power supply, and Reed-Solomon coding.The DAC38RF82EVM also offers a wide frequency response. The product includes an adjustable gain option, allowing for signal amplification when needed. Additionally, the device features low-latency filtering, which helps to reduce latency when transmitting signals, and gyroscope functions, which help to ensure accuracy and stability when measuring angular velocity. In addition, the DAC38RF82EVM is compatible with TI’s integrated set of evaluation tools, such as TI’s Code Composer Studio (TM) Integrated Development Environment (IDE). These tools offer various features that help speed up the development process, such as code completion, debugging capability, editing, and more.

Working Principle

The DAC38RF82EVM uses a sigma-delta modulator to convert digital data, such as audio or video, to analog signals that can be used by a variety of output devices, such as an amplifier or loudspeaker. The modulator performs a two-step conversion process: first, the digital data is converted into a pulse width modulated (PWM) signal, and then the PWM signal is converted into an analog signal. The digital data is sent to the modulator, which then filters and encodes the data into a signal that is suitable for the output devices. The digital output of the DAC38RF82EVM is fed into the Reed-Solomon encoder which ensures all transmitted data is accurately represented. The encoder then compresses and scrambles the digital data before it is sent to the analog output stage, where it is further manipulated and adjusted to the desired parameters by using the filtering and gain control options offered by the device.

Conclusion

The DAC38RF82EVM is a powerful evaluation module (EVM) that provides an excellent choice for digital-to-analog converters applications in industrial automation, sensor measurements, automotive control, communications, and more. The device offers a wide range of features, such as a 204MHz sampling rate, 14-bit resolution, a sigma-delta modulator, a 128-tap digital filter, a built-in power supply, and Reed-Solomon coding. In addition, the evaluation module is also compatible with TI’s integrated set of evaluation tools. With all its great features, the DAC38RF82EVM is a great choice for your digital-to-analog converter applications.
