IntroductionThe DAC900EVM is a digital-to-analog converter (DAC) evaluation board that is designed to provide a low-cost, easy-to-use platform for evaluating DAC performance. It allows users to quickly configure and evaluate multiple DACs from Texas Instruments\' DAC Series.Application FieldThe DAC900EVM is a versatile evaluation board, suitable for a variety of applications in industrial, automotive, and consumer-level designs. It is well-suited for audio-related applications, as it provides high-quality and low-noise audio output. It is also suitable for applications that require high speed response, such as in embedded control systems, high speed telecommunications devices, or high-precision measurement systems.The DAC900EVM is suitable for automotive and industrial applications due to its power efficiency, flexibility, accuracy, and distortion-free audio performance. The DAC900EVM also helps in reducing costs and development time thanks to its wide variety of features that make debugging and testing simpler.Working PrincipleThe DAC900EVM evaluation board is based on a digital-to-analog conversion principle. The evaluation board supports several of Texas Instruments DACs, including the TMS320C6740A and MSP430F6736A devices. The evaluation board uses an analog-to-digital converter (ADC) to sample the input signal and convert it into a digital format that can be processed into a DAC output.The equivalent circuit of the DAC900EVM works in two main stages. First, the digital signal is received from the ADC and goes through the digital signal processor (DSP) where its information is converted into a time-domain waveform. The waveform is then inputted into the DAC, which converts it into an analog signal.The analog signal is then fed into a summation circuit where the DAC output is summed with an external reference voltage which is set by the user. This voltage is then output to the amplifier, which outputs the amplified signal to the load.ConclusionThe DAC900EVM evaluation board is designed to evaluate Texas Instruments’ DAC series. The evaluation board is suitable for industrial, automotive, and consumer designs, as it provides high quality and distortion-free audio performance. It also helps reduce costs and development time, allowing users to quickly configure and evaluate multiple DACs. The DAC900EVM works based on a digital-to-analog conversion principle, where the digital signal is initially sampled by an ADC and then processed into analog output.
