Features
- 1) They facilitate direct serial control from a microcomputer of volume (main volume) 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) Input amp can be used for gain adjustment, and matrix surround yields powerful sound. 4) Stable standard voltage supply and built-in I / O buffer mean that few attachments are needed. SSOP32 package designed to save space. FAbsolute maximum ratings (Ta = 25_C) 5) Op.
