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 complete the PASC processor, a SAA2003 stereo filter and codec is required.

FEATURES

• Wide operating voltage range: 2.7 to 5.5 V

• Low power consumption: 13 mW; 3.0 V

• Low power decode mode: 1 mW; 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).
