Philips Semiconductors
Stereo-tone/volume control circuit
Product specification
TDA1524A
GENERAL DESCRIPTION
The device is designed as an active stereo-tone/volume control for car radios, TV receivers and mains-fed equipment.
It includes functions for bass and treble control, volume control with built-in contour (can be switched off) and balance.
All these functions can be controlled by d.c. voltages or by single linear potentiometers.
Features
Few external components necessary
Low noise due to internal gain
Bass emphasis can be increased by a double-pole low-pass filter
Wide power supply voltage range.
