TAS3002
Description
The TAS3002 device is a system-on-a-chip that replaces conventional analog equalization to perform digital parametric equalization, dynamic range pression, 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 or from an external EEPROM through the I2C master port. The TAS3002 device also has an integrated 24-bit stereo codec with two I2C-selectable, single-ended inputs per channel. The digital parametric equalization consists of seven cascaded, independent biquad filters per channel. Each biquad filter has five 24-bit coefficients that can be configured into many different filter functions (such as band-pass, high-pass, and low-pass). The internal loudness contour algorithm can be controlled and programmed with an I2C mand. Dynamic range pression/expansion (DRCE) is programmable through the I2C port. The system designer can set...
