TAS3004PFB [Rochester]

The TAS3004 is a system-on-a-chip digital audio processor that provides high-quality, soft digital volume, bass, and treble control. It features a 24-bit stereo codec with two I2C-selectable, single-ended inputs per channel. The device includes seven cascaded, independent biquad filters per channel for parametric equalization, programmable dynamic range compression/expansion (DRCE), and a loudness contour algorithm. It supports 13 serial interface formats (I2S, left justified, right justified) with data word lengths of 16, 18, 20, or 48 bits, and sampling frequencies of 32 kHz, 44.1 kHz, or 48 kHz. The device uses a system clock generated by an internal PLL with external MCLK reference of 256fS or 512fS. It has six internally configurable general-purpose input (GPI) terminals for control of volume, bass, treble, and equalization.
