DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC1853 MATRIX SURROUND IC WITH I2C BUS The µPC1853 is a phase shift matrix surround IC. Only 2 speakers on the front side implement wide sound expansion, and by adding rear speakers, rich three-dimensional sound can obtained. The µPC1853 can perform all controls (mode switching, volume control and so on) through the I2C bus. FEATURES • Any control is possible through the I2C bus. • Surround effect can be realized by only 2 speakers on the front side. • On-chip tone (bass and treble) control circuit. • Level-adjustable output pin for heavy bass sound. • Level-adjustable output pin for AV amplifier. • µPC1853-01 : • µPC1853-02 : On-chip low boost circuit. On-chip volume and balance control circuits.
