características:
  • · Equipped with 6 single ended stereo input selectors.
    · Built-in input gain controller suitable for mobile audio.
    · Volume input terminal can be used as a microphone input terminal since its impedance remains constant even if volume setting is changed.
    · Bi-CMOS process is suitable for the design of low current and low energy. It also provides more quality for Bi-CMOS small scale regulator and heat in a set.
    · The package of this IC is SSOP-A32. Sound input terminals and output terminals arrangement is optimized for easy and fast layout of PCB pattern. At the same time, it minimizes PCB area.
