LA2650 General Description


The LA2650 is a bass boost IC developed for use in minicomponent stereo systems, TV sets, and radio/cassette player products. The cutoff frequency is determined by external capacitors, and the boost gain, addition level, and boost on/off state can be controlled by a microcontroller.

LA2650 Maximum Ratings

Parameter Symbol Conditions Ratings Unit
Maximum supply voltage VCC max   12 V
Allowable power dissipation Pd max Ta 70°C 450 mW
Operating temperature Topr   20 to +75 °C
Storage temperature Tstg   40 to +150 °C

LA2650 Features

• The bass boost gain is variable over a maximum range of 20 to 35 dB in 5-dB steps, and the addition level into the left and right channels can be controlled over a 0 to 35 dB range in 3-dB and 5-dB steps. This allows an optimal boost for the source and volume to be acquired using microprocessor control.
• Includes two AGC circuits on chip: a level limiter (2 V rms) for the maximum input in low-frequency boost mode and a non-clipping limiter (i.e. clip prevention) circuit.
• Can be switched between 2D and 3D systems.
