The PCM1803ADBR is a special purpose data acquisition (DAQ) integrated circuit (IC) produced by Texas Instruments (TI). It is an audio codec that integrates both analog-to-digital (ADC) and digital-to-analog (DAC) converters into a single chip. The PCM1803ADBR is designed for use with portable audio and video devices, such as digital audio recorders and portable DVD players.
The PCM1803ADBR integrates an analog input interface, an analog output interface, a sample rate converter, and a Delta-Sigma ADC and DAC. The analog input interface is designed to accept an unbalanced stereo audio signal and convert it to a differential signal. The analog output interface supports both balanced and unbalanced stereo audio signals. The sample rate converter supports sample rates of 32-48kHz.
The Delta-Sigma ADC and DAC, also known as a Sigma-Delta ADC/DAC, are each capable of 16 bit, 20 bit, and 24 bit sample resolution. The ADC is capable of sampling rates up to 384kHz, while the DAC is capable of sampling rates up to 192 kHz. The PCM1803ADBR also integrates digital filters that can be used to reduce background noise or alter the frequency response of the audio signal.
The PCM1803ADBR has numerous application fields, including portable audio and video devices, consumer electronics, and automotive displays and entertainment systems. It is an ideal choice for design engineers looking for a single IC solution that can both encode and decode audio signals with high quality and accuracy.
In terms of its working principle, the PCM1803ADBR is based on the process of sigma-delta modulation. Sigma-delta modulation is a form of pulse-density modulation used to convert analog signals into digital signals. It works by converting the analog signal into a sequence of pulses, also known as a pulse code. The pulses are then quantized and converted into a digital data stream.
Once the analog signal is encoded as a pulse code, the pulse code is passed through a low-pass filter. The filter reduces the noise that is present in the signal, resulting in a smoother digital signal. This filtered signal is then passed through a DAC to convert it back into an analog signal.
Sigma-delta modulation provides several benefits over other forms of digital-analog conversion, such as pulse-width modulation. Firstly, it has a much higher accuracy, meaning that it can create signals with a much lower noise floor. Secondly, it reduces the complexity of the circuit needed to convert analog signals into digital signals, reducing the number of components that are required.
Overall, the PCM1803ADBR is a versatile, high-performance data acquisition IC. It provides a single IC solution for encoding and decoding audio signals, and its Sigma-delta modulation provides a number of benefits over other forms of digital-analog conversion. With its multiple application fields and support for various sample rates, the PCM1803ADBR is an excellent choice for design engineers in need of a reliable and powerful audio codec.
