TAS3002 Digital Audio Process

The TAS3002 device is a system-on-a-chip that replaces conventional analog equalization to perform digital parametric equalization, dynamic range compression, and loudness contour. Additionally, this device provides high-quality, soft digital volume, bass, and treble control. All control parameters are uploaded from an outside MCU through the I2C slave port .

Features

• Programmable seven-band parametric equalization
• Programmable digital volume control
• Programmable digital bass and treble control
• Programmable dynamic range compression/expansion (DRCE)
• Programmable loudness contour/dynamic bass control
• Configurable serial port for audio data
• Two input data channels that can be mixed with digital data from the analog-to-digital converter (ADC) of the codec (analog input). These channels are controlled by I2C commands.
• Three output data channels: Left and right data go through equalization; bass, treble, DRCE, and volume to SDOUT1; SDOUT2 mixes l.
