LM1036
Dual DC Operated Tone/Volume/Balance Circuit
General Description
The LM1036 is a DC controlled tone (bass/treble), volume
and balance circuit for stereo applications in car radio, TV
and audio systems. An additional control input allows loud-
ness compensation to be simply effected.
Four control inputs provide control of the bass, treble, bal-
ance and volume functions through application of DC volt-
ages from a remote control system or, alternatively, from four
potentiometers which may be biased from a zener regulated
supply provided on the circuit.
Each tone response is defined by a single capacitor chosen
to give the desired characteristic.
Features

n Tone control, ±15 dB typical
n Channel separation, 75 dB typical
n Low distortion, 0.06% typical for an input level of 0.3
Vrms
n High signal to noise, 80 dB typical for an input level of
0.3 Vrms
n Few external components required
