AA8334 Agamem Microelectronics Inc. SURROUND PROCESSOR PRELIMINARY ■ DESCRIPTION AA8334 is an analog stereo enhancement processor. It creates a stereo image with depth in three dimensions from ordinary left and right input channels. The patented QXpander (*1) technology developed by QSound Labs, Inc., is faithfully implemented by Agamem(*2). Note 1: QXpander® is a stereo to 3D enhancement processor and is a trademark of QSound Labs, Inc... Note 2: Agamem has got licensing agreement of QXpander® from QSound Labs, Inc... ■ FEATURES • Sound spreading can be easily adjusted using an external VR. • Few external components required through use of internal filter circuit. • QXpander on/off switching at TTL level. ■ APPLICATIONS • Sound enhancement processor for LCD TV, home theater, PC, notebook and car stereo. ■ BLOCK DIAGRAM Vcc LIN 3DF1 3DF2 3DF3 3DF4 DET LOUT 16 15 14 13 12 11 10 9 + - AA8334 1 2 3 4 5 6 7 8 RIN VREF S/3D FC SPC 3DIN ROUT GND ©Copyright Agamem Microelectronics Inc. 1 www.agamem.com.tw 2008/3/28 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.

When the power supply of AA8334 is switched off, the pop noise occurs. We recommend muting the pop noise. The way is that the power supply of AA8334 is switched off after the power supply of the follow power amplifier is switched off. ←Tvoff→ Vcc=8V Vcc waveform (Pin 16) Vcc=0V Vdeth DET pin waveform (Pin 10) Vdet1 Note 8: We recommend using the regulator for the power supply which occurs the ripple.
