LC75374E
Overview
The LC75374E is an electronic volume and tone control circuit that provides volume, balance, fader, bass and treble, super bass, input switching, and input and output level controls and requires a minimal number of external ponents to implement these functions.
Features
- On-chip buffer amplifiers minimizes the number of external ponents.
- Built-in reference voltage generator for the analog ground.
- All controls can be set using the serial data input circuit (CCB).
Functions
- Volume: 0d B to
- 79d B (in 1-d B steps) and
- ∞d B for a total of 81 positions. A balance function can be implemented by controlling the left and right channels independently.
- Fader: Allows either the rear or the front channel outputs to be attenuated over 16 positions. (0 to
- 20d B in 2d B steps,
- 20 to
- 25d B in a 5d B step,
- 25 to
- 45d B in 10d B steps,
- 60d B, and
- ∞d B for a total of 16 positions.)
- Bass and treble: NF-type tone control circuits are form- ed using external CR circuits. The bass and...
