QX2130

·Speaker systems for desktop and notebook multimedia personal computers, televisions, audio equipment, video
games and other devices

The QX2130 is designed as a sound enhancement sound processor based on QSOUND's QX pander technology, and produces virtual 3D sound from ordinary audio signals. This IC requires no special encoding of input signals or additional speakers, and so simplifies the development of high-value-added personal computers, televisions and audio products.

QX2130 has eight features. (1)Virtual 3D sound from ordinary audio signals. (2)No special encoding signals are necessary. (3)Three enhanced modes:QX1 pro listening; QX2 wide listening; QX3 wow for games. (4)Internal functions for personal computers: power saver function, output muting function and stereo bypass function. (5)TTL-compatible control pins (at 5V). (6)Low noise (45mVrms). (7)Low power consumption. (8)Available in SSOP-A20 pin package or SDIP22 pin package. Those are all the main features.

Some absolute maximum ratings of QX2130 have been concluded into several points as follow. (1)Its power supply voltage would be 13V. (2)Its power dissipation would be 1000mW or 750mW. (3)Its operating temperature range would be from 0°C to 70°C. (4)Its storage temperature range would be from -55°C to 125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of QX2130 are concluded as follow. (1)Its supply current QX mode would be min 1.3mA and typ 3.0mA and max 5.2mA. (2)Its supply current stereo mode would be min 1.3mA and typ 3.0mA and max 5.2mA. (3)ts supply current power saving mode would be typ 230uA and max 500uA. (4)Its channel balance would be min -1.5dB and typ 0dB and max +1.5dB. (5)Its output current would be max +/-1mA. (6)Its input impedance would be typ 50kohms and typ 75kohms and max 100kohms. (7)Its load capacitance would be max 1000pF. (8)Its output impedance would be max 200ohms. And so on.
