Product Details

Description



Features:

• Built-in buffer amplifiers allow applications to b mplemented with few external components.
• A VDD/2 reference voltage generation circuit is provided on chip.


Application

• Volume control: From 0 to 79 dB in 1-dB steps plus
° for a total of 81 settings. Since the left and right
   levels can be set independently, this function can also be
   used to implement a balance function.
• Fader: Attenuates either the rear or front channels to
   one of 16 levels. (Provides 16 settings, namely, from 0
   to 20 dB in 2-dB steps, from 20 to 25 dB in one
   5-dB step, from 25 to 45 dB in 10-dB steps, 60 dB,and °.)
• Bass and treble controls: Forms an NF-type tone control
   circuit (LUX type) using external capacitors. Provides
   15 settings each for the bass and treble controls.
• Loudness control: A loudness function can be
   implemented by attaching external RC circuits at the
   taps provided from the volume control resistor ladder
   starting at the 20-dB position.
• The input signal can be selected from one of three inputs
   for each of the left and right channels. The input signal
   can be amplified by between 0 and +18 dB in 6-dB steps.
• Serial data input: Supports CCB* format communication
   with the system controller.
