TDA1524A is an active stereo-tone/volume control circuit designed 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.
The Philips TDA1524A is an integrated circuit designed as an active stereo-tone and volume control circuit. It is intended for use in car radios, TV receivers, and mains-fed equipment. The device includes functions for bass and treble control, volume control with a built-in contour that can be switched off, and balance control. These functions can be controlled by d.c. voltages or by single linear potentiometers.
