BH3856S

BH3856S / BH3856FS Audio ICs 2-wire serial sound control IC BH3856S / BH3856FS The BH3856S and BH3856FS are signal processing ICs designed for volume and tone control in televisions, mini component stereo systems, and other audio products. Their two-line serial control (I2C BUS) enables them to control volume and tone on the basis of signals from a microcomputer, etc. !Applications Televisions, [Video equipped television], personal computer televisions, mini component stereo systems, car stereos. !Features 1) I2C BUS facilitates direct serial control from a microcomputer of volume (main volume), balance (left / right), and tone (bass, treble). DC control is also possible. 2) Volume is produced by a low-distortion, low-noise VCA. Designed to minimize step noise. 3) Stable standard voltage supply and built-in I/O buffer mean that few attachments are needed. SSOP-A32 package designed to save space. 4) Matrix surround yields powerful sound. !Absolute maximum ratings (Ta = 25°C) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature BH3856S BH3856FS Symbol Vcc Pd Topr Tstg Limits 10.0 1200 ∗1 850 ∗2 −40~+85 −55~+150 Unit V mW °C °C ∗1 Reduced by 12mW for each increase in Ta of 1°C over 25°C. ∗2 Reduced by 6.8mW for each increase in Ta of 1°C over 25°C. !Recommended operating conditions (Ta = 25°C) Parameter Power supply voltage Symbol VCC Min. 6.0 Typ. 9 Max. 9.5 Unit V Note : I2C BUS is a registered trademark of Philips.
