LM4610 Datasheet | National Semiconductor

Description The LM4610 is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems. It also features National’s 3D-Sound Circuitry which can be externally adjusted via a simple RC Network. An additional control input allows loudness pensation to be simply effected. Four control inputs provide control of the bass, treble, balance and volume functions through application of DC voltages 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 National 3-D Sound Wide supply voltage range, 9V to 16V Large volume control range, 75 d B typical Tone control, ± 15 d B typical Channel separation, 75 d B typical Low distortion, 0.06% typical for an input level of 0.3 Vrms n High signal to noise, 80 d B typical for an input level of 0.3 Vrms n Few external ponents required n n n n n n Block and Connection Diagram Dual-In-Line Package DS101125-1 Order Number LM4610N See NS Package Number N24A © 1999 National Semiconductor Corporation DS101125 .national.
