Product specification
Stereo-tone/volume control circuit
TDA1526
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 DC 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.
