The ISL5961EVAL2 evaluation board from Intersil is a high performance digital-to-analog converter (DAC). The board combines DAC performance, low noise, high dynamic range, good linearity, and low power consumption in one device. Designed to provide a wide range of data conversion solutions for digital audio and multimedia applications, the board features a dual 10-bit, 8ns wide, low power, reliable DAC, the ISL5961. This evaluation board provides a simple and convenient platform for characterizing the DAC and the related front-end circuitry and components.

The evaluation board includes analog inputs, configurable output drivers, a low power DAC core, a power supply filter, and two 10-bit flash DACs. The analog input section is provided by a high precision differential amplifier. The signal from the amplifier is buffered and then sent to the low power DAC core. The board also contains an output driver section, which consists of two 10-bit flash DACs, a resistor ladder for setting the output levels, and an active output driver to drive the analog output. The digital inputs are provided via the serial I/O pins of the IC, and the analog outputs are buffered and delivered to the output driver section. Finally, a power supply filter is included to ensure that a clean power source is provided to the DAC core.

In terms of performance, the ISL5961EVAL2 board delivers excellent linearity and a wide dynamic range. It has a low power consumption of 50 mW, as well as an output noise performance of 50µVRMS. This makes the board suitable for use in a wide range of audio and multimedia applications. The board also offers a software controlled gain range of up to +/- 6 dB, as well as a number of programmable parameters. In addition, the board is designed to be compatible with various applications, including consumer audio, instrumentation and automation.

In terms of working principle, the board uses a pulse-code modulation (PCM) type of data conversion. This type of conversion is used to convert a continuous signal into a sequence of digital codes, which can then be processed by a digital signal processor (DSP) for further processing. The board also utilizes a variety of other digital techniques, such as noise shaping, error correction, and clock synchronization, to ensure accurate data conversion while consuming minimal power.

Overall, the ISL5961EVAL2 evaluation board provides a comprehensive solution for digital-to-analog conversion and is suitable for a wide range of applications. Its dual 10-bit flash DACs provide excellent linearity, low power consumption, and excellent noise performance, making it an ideal solution for applications such as consumer audio, instrumentation, and automation. With its vast range of programmable features, the board ensures a high degree of flexibility and precision in data conversion.
