Introduction

Data Acquisition (DAQ) is an essential and broadly applicable field of electrical engineering that have been established over decades. It enables the acquisition, processing, and display of analog signals from digital or analog sensors. Analog to Digital (AD) and Digital to Analog Converters (DAC) are two of its subfields. In this article, we will focus on the latter: DACs and their common application of the CS43131-CNZ within the DAQ domain.

Types of Digital to Analog Converters

DACs are subdivided into two main categories, series converters and parallel converters. In the series type, the output is derived from the binary equivalent of the input code. This approach is mainly used in voltage-output DACs and it may be implemented through several integrated circuits. Parallel type DACs, on the other hand, are generally used for current-output converters and takes an alternative approach to derive the output from multiple digital-to-analog conversion elements that are connected in parallel.

The CS43131-CNZ DAC Application Field and Working Principle

The CS43131-CNZ series families, developed by Cirrus Logic, are voltage-output digital to analog converters. Establishing CS-42 mentioned before as a base efficiency, CS43131-CNZ provides a higher SNR and low THD+N characteristics given that it is a low-cost current-nuclear DAC. This series is specifically designed for consumer, automotive and professional audio applications. The CS43131-CNZ consists of an array of 19-bit R-2R ladder resistors, allowing for voltage outputs of up to 4V. Aside from its integrated R-2R, it also features an I2S for easy communication between the converter and the system host, as well as an on-board 30-bit noise shaping filter for improved sound quality. Additionally, the converter also offers programmable input muxes and attenuators to allow for efficient control of the converter’s frequency response and resolution.At the heart of the CS43131-CNZ is its advanced, patent-pending, fourth-order ΔΣ modulator, which works to convert the input digital signal into an analog equivalent. The CS43131-CNZ includes an Ultralow Jitter architecture and noise shaping filter, allowing for a low-noise DAC output with wider dynamic range in comparison to traditional audio converters that use first-order Delta-Sigma DACs.

Conclusion

The CS43131-CNZ digital to analog converter is a powerful and efficient tool for audio applications. Its innovative features and high-resolution, low-noise DAC output make it well-suited for a variety of audio applications such as audio streaming, professional or automotive systems. The flexibility of the on-board programming tools, as well as its wide dynamic range, make it an ideal choice for optimising performance in higher fidelity audio systems.
