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
components to implement these functions.
Functions
Volume: 0dB to –79dB (in 1-dB steps) and –
∞dB 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 –20dB in 2dB steps, –20 to –25dB in a 5dB
step, –25 to –45dB in 10dB steps, –60dB, and
–
∞dB for a total of 16 positions.)
Bass and treble: NF-type tone control circuits are form–
ed using external CR circuits. The bass
and treble can be controlled from 0dB
to +11.9dB (in 1.7dB steps) for a total
of 15 positions.
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.
Features
On-chip buffer amplifiers minimizes the number of
external components.
Built-in reference voltage generator for the analog
ground.
All controls can be set using the serial data input circuit
(CCB).
