ORDERING INFORMATION EXTENDED TYPE NUMBER SAA2003H Note PACKAGE PINS 44 PIN POSITION QFP(1) MATERIAL plastic GENERAL DESCRIPTION SAA2003 The SAA2003 performs the sub-band filtering and audio frame codec functions in the Precision Adaptive Sub-band Coding (PASC) system. It can be used as a stand-alone decoder for playback only applications, but requires the addition of an Adaptive Allocation and Scale Factor processor (SAA2013) in order to perform PASC encoding in a DCC record system. CODE SOT307 1. When using reflow soldering it is recommended that the Dry Packing instructions in ...
