INTEGRATED CIRCUITS DATA SHEET TDA1524A Stereo-tone/volume control circuit Product specification File under Integrated Circuits, IC01 September 1987 Philips Semiconductors Product specification Stereo-tone/volume control circuit GENERAL DESCRIPTION TDA1524A 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.
