PCM2900CDBR Typical application Circuitry

PCM2900CDBR

The PCM2900CDBR is a USB audio codec integrated circuit developed by Texas Instruments. This chip functions primarily as an audio interface, converting analog audio signals to digital data and vice versa, enabling easy interfacing of audio hardware with computers via USB.

Application Scenarios

The PCM2900CDBR is often used in USB headphones, audio recording interfaces, USB speakers, and any other audio application where digital audio data needs to be transferred via USB.

Parameter Features

Notable features of the PCM2900CDBR include:

- Integrated USB interface.

- 16-bit analog-to-digital (ADC) and digital-to-analog converters (DAC).

- Sampling rate up to 48 kHz.

- USB-powered, requiring no external power source.

Application Scenario - USB Audio Interface: Circuit Connection Method

1. USB Connection: Connect the USBDM (pin 28) and USBDP (pin 27) of the PCM2900CDBR to the corresponding D- and D+ pins of a USB connector. This interface will handle the digital audio data transfer.

2. Analog Audio Input: For capturing analog audio, connect a microphone or line input to the VINL (pin 3) and VINR (pin 6) pins for left and right channels, respectively.

3. Analog Audio Output: To output digital audio to analog, connect VOUTL (pin 14) and VOUTR (pin 17) to an external amplifier or directly to speakers.

4. Power Supply: The PCM2900CDBR is powered directly from the USB connection, with VBUS (pin 30) connected to the USB power line, and DGND (pins 18, 19, 25, 26) to ground.

Circuit Design Considerations

- Signal Integrity: Ensure minimal noise in the analog signal path to maintain audio quality.

- PCB Layout: Carefully design the PCB to separate digital and analog sections, reducing interference.

- Grounding: Use a proper grounding scheme to avoid ground loops which can introduce noise.

- USB Compliance: Design the USB interface in compliance with USB standards for compatibility.

Using the PCM2900CDBR in a USB audio interface highlights its ability to facilitate high-quality audio data transfer between analog and digital domains, making it ideal for computer-based audio recording and playback systems.
