The TAS2521 is a low power digital input speaker amp with support for 24-bit digital I2S data mono playback. In addition to driving a speaker amp up to 4-R, the device also features a mono headphone driver and a fully programmable miniDSP for signal processing. The digital audio data format is programmable to work with popular audio standard protocols (I2S, left/right-justified) in master, slave, DSP and TDM modes. The fully programmable miniDSP can support several functions such equalization for audio, multi-band DRC, tone generation and several other user defined functions. An on-chip PLL provides the high-speed clock needed by the digital signal-processing block.
