HI5741-EVS Evaluation Board OverviewThe HI5741 evaluation board (EVS) is a digital-to-analog converter (DAC) board from Infineon Technologies. It features a 32-bit DAC, 15-bit digital-to-analog conversion, a gamma correction circuit, and a 10-bit analog-to-digital converter (ADC).The HI5741 EVS is designed to evaluate Infineon’s HI5741 DAC and other related components. The board contains a wide range of features, such as: a rich set of digital, analog and power components, an integrated microcontroller, an embedded CPU and RAM, a variety of digital-to-analog and analog-to-digital converters, a programmable clock, and several integration peripherals.The HI5741 EVS enables the development and evaluation of a wide range of applications, including medical imaging systems, signal processing systems, consumer audio applications, and automotive audio systems.Application Field of HI5741-EVSThe HI5741 EVS offers a high-performance, low-power solution for digital-to-analog conversion. It can be used in a variety of applications, including: medical imaging systems, signal processing systems, consumer audio applications, automotive audio systems, and power measurement systems.The HI5741 EVS is ideal for medical imaging systems due to its high-speed, full-bodied DAC capabilities. It can achieve a maximum output of 2.2 Vpp and a sampling rate of up to 66.5 kHz, which enables detailed image renderings.For signal processing, the HI5741 EVS supports a wide range of features including a programmable gain amplifier, low-noise ADC, and selectable sigma-delta modulators. These features make the board perfect for signal processing-related audio signal processing applications.The HI5741 EVS is also suitable for automotive audio applications due to its wide array of digital/analog components and its easy-to-use management and monitoring tools. It can be used to develop automotive audio systems, such as car radio receivers and alphanumeric display systems.The HI5741 EVS is also suitable for power measurement systems since it features an integrated microcontroller, 10-bit ADC, and dedicated GPIO pins for monitoring power supply status. This makes the board suitable for both small and large-scale power management systems.Working Principle of HI5741-EVSThe HI5741 EVS is based on TI’s 5541 high-performance DAC. The board utilizes a dual-phase lock loop (DPLL) oscillator to generate a reference clock signal for the DAC. The clock is then used for the synchronous DMA transfer of data between the microcontroller and the DAC.The HI5741 EVS includes two DACs, one for the reference and one for the output. The onboard ADC and DAC provide an analog-to-digital conversion rate of up to 2.5 Msps.For gamma correction, the HI5741 EVS provides a switchable gamma correction circuit. This circuit is used to correct output non-linearity and reduce output noise.ConclusionThe Infineon HI5741-EVS Evaluation Board is a powerful DAC board designed to support a wide range of applications including medical imaging systems, signal processing systems, consumer audio applications, automotive audio systems, and power measurement systems. The board features a 32-bit DAC with a full-bodied 2.2 Vpp output, an integrated microcontroller, an embedded CPU and RAM, a programmable clock, and a wide array of digital and analog components. It also includes a gamma correction circuit for output non-linearity correction and noise reduction.
