PCM2906DBR

The PCM2906DBR is an audio CODEC from Texas Instruments which is used for audio signal conversion from digital devices to analog devices and vice versa. This device is a single-chip stereo analog-to-digital/digital-to-analog (A/D and D/A) converter with an integrated USB interface. It has an integrated hardware sample rate converter which allows for multi-channel playback and recording for audio and multimedia applications. It is ideal for applications such as multimedia speakers, portable DVD players, karaoke machines, alarm systems, and digital rice-cookers.

The PCM2906DBR comes with integrated interface logic and 480 Mbps USB1.1 connectivity which supports full-speed transmissions. It has a two-channel mono/stereo A/D and D/A converter and is capable of recording with up to 24-bit precision at sample rates up to 96 kHz. It has stereo line-level inputs and switchable outputs which can be used with different load types like headphones and stereo speakers. It also supports both USB and I2C bus interfacing, as well as GPIO control. The USB port can be used to connect the PCM2906DBR to any USB-enabled device such as a laptop, a PC or embedded system.

The PCM2906DBR is a single-chip stereo A/D and D/A converter. It can be used to convert digital input audio signals into analog outputs such as headphones and stereo speakers. It can also convert analog input signals into digital output signals such as for recording devices. It features very low distortion, low noise, and a high signal-to-noise ratio. It has digital filter characteristics which provide excellent sound quality.

The PCM2906DBR has a working principle which is based on patented Texas Instruments converter architecture. It has four different operations modes including two-channel mono/stereo mode and master I2S mode. In two-channel mode, each channel is independently driven and can be used with different load types like headphones and stereo speakers. In master I2S mode, the PCM2906DBR is the clock master and generates the S/PDIF clock signals required to synchronize audio data. It also provides GPIOs which allow it to be controlled via external signals.

The PCM2906DBR is used in a wide range of applications, especially in multimedia sound systems, portable DVD players, and alarm systems. It can be used to record and playback audio data at 24-bits precision and sample rates up to 96 kHz. It is suitable for professional audio applications such as post production, recording and mastering, due to its low distortion, low noise and high signal-to-noise ratio. The PCM2906DBR is a cost-efficient and easy-to-use device ideal for many audio and multimedia applications.

The PCM2906DBR is one of the most versatile CODECs, as it can be used for a wide range of audio and multimedia applications. Its versatile interfaces and multiple operating modes together with its low distortion, low noise and high signal-to-noise ratio make the PCM2906DBR an ideal choice for applications requiring high-quality audio performance.
