LC75348 - Single-Chip Electronic Volume and Tone Control System

Key Features

  • Built-in buffer amplifiers reduce the number of external components required.
  • Fabricated in a silicon gate CMOS process for minimal switching noise from built-in switches and minimal switching noise even when there is no input signal.
  • Built-in zero cross circuits minimize switching noise when input signals are present.
  • Built-in VDD/2 reference voltage generator circuit.
  • All functions are controlled from serial data. Supports the CCB bus.

Ordering number : ENN7308 CMOS IC LC75348, 75348M Single-Chip Electronic Volume and Tone Control System Overview The LC75348 and LC75348M are electronic volume and tone control ICs that provide volume, balance, 2-band equalizer, input gain control, and input switching functions while requiring a minimal number of external components. Package Dimensions unit: mm 3196-DIP30SD [LC75348] 27.0 30 16 • Volume: 81 levels: 0 dB to –79 dB (in 1 dB steps) and –∞. The left and right channels are controlled independently, allowing a balance function to be implemented. • Bass: Peaking characteristics bass control with ±20 dB range in 2 dB steps. • Treble: Shelving characteristics treble control with ±10 dB range in 2 dB steps.
