TDA1524A

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.
