SAA2013 Datasheet | Philips Semiconductors

FEATURES - Wide operating voltage range: 2.7 to 5.5 V - Low power consumption: 13 m W; 3.0 V - Low power decode mode: 1 m W; 5.0 V - Sleep mode for low power and low Electromagnetic Interference (EMI) - Sophisticated allocation algorithm - Optimum sound quality - Three-wire L3 bus microcontroller interface - Stereo or 2-channel mono recording - Small surface mounted package (QFP; SOT307). ORDERING INFORMATION PACKAGE TYPE NUMBER PINS SAA2013H Note 44 PIN POSITION QFP(1) MATERIAL plastic GENERAL DESCRIPTION The SAA2013 performs the adaptive allocation and scaling function in the Precision Adaptive Sub-band Coding (PASC) system. It is not required in playback only applications, and is only used during recording. To plete the PASC processor, a SAA2003 stereo filter and codec is required. CODE SOT307-2 1. When using reflow soldering it is remended that the Dry Packing instructions in the “Quality Reference Pocketbook” are followed. The pocketbook can be ordered using the code 9398 510 34011.
