Data Acquisition is a process of analyzing, measuring and recording data, in order to draw useful conclusions from it. ADCs and DACs are the most common tools used for this purpose. ADC and DAC stands for Analog-to-Digital Converter and Digital-to-Analog Converter respectively and they convert a digital signal into an analog signal and vice versa. Special purpose devices are designed to perform a specific task and the PCM1808QPWRQ1 is one such example. In this article, we’ll discuss the application field as well as the working principle of the PCM1808QPWRQ1.

Application Field

The PCM1808QPWRQ1 is a low-noise, low-power, 4-channel Delta Sigma analog-to-digital converter (ADC) designed to perform high quality audio signal acquisition. It has the ability to convert up to four analog audio signals into high resolution digital signals. The PCM1808QPWRQ1 is ideal for use in stereo and multi-channel audio applications such as professional portable audio and broadcast, as well as home and car audio systems.

The PCM1808QPWRQ1 offers an Analog Front End (AFE) that supports sampling rates up to 192 kHz, making it suitable for high quality audio applications. It has an onboard high accuracy clock module that supports both oscillator and crystal clock modes, making the clock control process hassle free. The 77 dB dynamic range and selectable digital output formats of the device ensures high quality digital audio signal acquisition. In addition, the programmable data formats and features offered by the PCM1808QPWRQ1 make it an ideal solution for high density audio signal recording.

Working Principle

The PCM1808QPWRQ1 consists of four analog input channels, a high resolution Delta Sigma analog-to-digital converter, and several digital functions. The analog input channels are converted into digital signals using the Delta Sigma converter. The Delta Sigma converter has the ability to convert low resolution analog inputs into high resolution digital outputs by using a differential signal. This ensures that the resulting digital signal is accurate, and of high quality.

The PCM1808QPWRQ1 can operate in either a parallel or serial communication interface mode. The device supports several different digital audio formats, including pulse-code modulation (PCM) and I2S data formats. The digital audio data is then outputted to the signal processing unit, which further processes the data in order to produce useful information.

Overall, the PCM1808QPWRQ1 is an ideal solution for high quality audio signal acquisition. It supports a wide range of digital audio formats, has a high dynamic range and accuracy, and is also very low power and low noise. The on-board clock module, data formats, and features make it an ideal choice for audio signal recording and processing applications.
