LC75374E Overview
EN5835 CMOS IC LC75374E Electronic Volume and Tone Control for Car Stereos 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.
LC75374E Key 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)
- Volume: 0dB to -79dB (in 1-dB steps) and -∞dB for a total of 81 positions. A balance function can be implemented by cont
- Bass and treble: NF-type tone control circuits are form- ed using external CR circuits. The bass and treble can be contr
- Input gain: The input signal can be amplified by 0dB to +18.75dB (in 1.25dB steps)
- Output gain: The fader output can be set to one of three settings: 0dB, +6.5dB, or +8.5dB
- Input switching: Both the left and right channels can be selected from one of four inputs
- Super bass: This circuit provides peaking characteristics (T type characteristics) and 11 position sett- ings
