Texas Instruments TAS3108IADCP

Description
The TAS3108/TAS31081A is an 8channel programmable audio digital signal processor (DSP) with a 48bit data path and 28bit coefficients. It has a maximum speed of 135 MHz and can process more than 2800 cycles per sample at 48 kHz. The TAS3108/TAS31081A has 1022 words of 48bit data memory, 1022 words of 28bit coefficient memory, 3K words of 54bit program RAM, and 5.88K words of 24bit delay memory. It also has two IFC ports for slave or master download, a soft volume controller, a dither generator, and an efficient log²/2 estimator. The TAS3108/TAS31081A is available in a 38pin thin shrink smalloutline package (TSSOP).
