The PCM1804DB is a precision 24 bit audio CODEC with an integrated programmable gain amplifier (PGA). The device is Digital Audio Interface (DAI) that converts analog signals to digital and vice versa. The PCM1804DB can accept up to four channels of audio data in a 24-bit resolution. The device supports both mono and stereo high-fidelity audio streaming with sampling rates up to 96kHz. It also supports single-data rates (SDR) and dual-data rates (DDR).

The PCM1804DB audio CODEC is used in a variety of applications such as audio recording, mixing, and playback for consumer electronics, automotive, professional audio, and multimedia applications. It is an ideal CODEC for home theaters, music players, digital cameras, portable audio players, and audio networking systems.

The PCM1804DB has several features that make it an ideal choice for such applications. It includes integrated stereo SSM2142 analog-to-digital (ADC) and digital-to-analog (DAC) converters for high-quality audio streaming. It is designed to handle a wide range of analog signal sources, including microphones, line-level inputs, and digital audio (I2S). The device can also accept multiple digital audio formats, such as PCM16, PCM32, Apple Lossless (ALAC), FLAC, and AIFF.

The PCM1804DB also features an integrated programmable gain amplifier (PGA) to control and adjust the volume level of the analog audio signals. It also allows users to control the gain and attenuation of the input signals, as well as the output signal\'s level. This feature allows users to optimize the sound quality and level for each of their audio sources.

The PCM1804DB\'s working principle is based on the conversion of electrical signals into digital formats. The device is capable of converting analog and digital audio streams into 24-bit audio with a maximum sample rate of 96 kHz. The device utilizes a multi-channel synchronous-serial port for communication with other digital audio devices. Once the data is converted, it is sent to a Digital Signal Processor (DSP) for processing. The DSP then converts the digital data back into analog signals and transmits them to the audio I/O ports.

The PCM1804DB is an ideal CODEC for applications requiring both high quality audio performance and low power consumption. It offers low-power operation and low jitter performance, making it suitable for many consumer audio, automotive, professional audio, and multimedia applications. The device also includes integrated mixing functions and an adjustable PGA for adjusting the input and output audio levels. The device supports both mono and stereo input signals and has an adjustable gain control for both the left and right channels.

The PCM1804DB is a powerful and flexible audio CODEC that can be used in a variety of applications. Its integrated PGA and low-power operation make it an ideal choice for high-fidelity audio streaming and digital audio applications, while its wide range of features such as mixing and adjustable gain control make it suitable for many different applications.
