The PCM3010DBR is a high-performance, low-power digital-to-analog converter (DAC) utilized in a wide variety of digital audio interface systems. This device is part of the CODEC (compression-decompression) family and is specifically designed for audio input and output applications demanding superior sound quality. The PCM3010DBR has been widely adopted in toys, displays, portable audio players, multimedia systems, and automotive applications.

The PCM3010DBR is a highly integrated audio codec that supports up to 24-bit resolution and a maximum sampling rate of 192 kHz. It integrates a stereo analog-to-digital converter (ADC), a stereo digital-to-analog converter (DAC), two headphone amplifiers (one per channel), independent volume control, and deflection interface circuitry, making it an ideal solution for portable audio systems. In addition, the PCM3010DBR supports the most common flexible audio protocol interfaces such as I²S, AC97, and TDM.

The PCM3010DBR supports input and output data formats including I2S, AC-Link, and TDM. It provides a digital interface that supports up to 24-bit audio resolution and sampling rates up to 192 kHz. This codec offers integrated voltage and current feedback loops, low distortion, and wide dynamic range. Other features include adjustable clock outputs, soft-start control, and 96 dB dynamic range.

The working principle of PCM3010DBR is based on the Delta-Sigma modulator. A Delta-Sigma modulator is an analog-to-digital converter (ADC) which breaks down an analog waveform into discrete digital values. This type of ADC is often referred to as a one-bit ADC because it only has to make a decision whether the analog waveform is either above or below a certain reference voltage. The PCM3010DBR takes advantage of this modulator to convert analog waveforms into digital values.

The PCM3010DBR digital-to-analog converter implements Delta-Sigma modulation to generate an analog waveform from the digital signal. It has a high-performance digital filter that reduces quantization noise, allowing it to produce a wide dynamic range of low-distortion sound. The integrated digital attenuators provide independent programmable attenuation of left and right audio channels.

The PCM3010DBR is a highly integrated, low-power audio CODEC that is used in a variety of audio interfaces, such as toys, displays, portable audio players, multimedia systems, and automotive applications. The modulator utilizes a Delta-Sigma modulator with a high-performance digital filter to reduce quantization noise, producing a wide dynamic range and low-distortion sound. The PCM3010DBR supports a number of flexible audio protocol interfaces, such as I²S, AC-Link, and TDM, and supports up to 24-bit resolution and a maximum sampling rate of 192 kHz.
