Description



Features:

• Volume: Provides 81 positions, from 0 dB to 79 dB (in 1-dB steps) and . A balance function can be implemented by controlling the left and right channels independently.
• Fader: This function can attenuate either the rear or the front outputs over 16 positions. (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/treble: Forms an NF-type tone control circuit (LUX type) with the addition of external capacitors. The base and treble controls each have 15 positions.
• Loudness: The volume resistor ladders are tapped starting at the 20-dB position. A loudness function can be implemented by adding external RC circuits at these taps.
• The signal can be selected from one of three inputs for each of the left and right channels. The input signals can be amplified from 0 to +18 dB in 6-dB steps.
• On-chip buffer amplifiers for a minimum of external components.
• Minimal switching noise due to fabrication in a silicongate CMOS process.
• Built-in reference voltage generation circuit
• Serial data input: Supports CCB format communication with the system controller
