AVT2050 B

The simplest acoustic amplifier consisting of only four elements: an integrated circuit, a resistor and two capacitors. The device is characterized by very good parameters thanks to which it is widely used, especially in battery equipment, it is also an attractive alternative for repairs of older playing equipment.
The integrated circuit that is the 'heart' of the amplifier includes short circuit and overload protections. The maximum power that can be obtained is 3 W. The source of power in the portable equipment can be galvanic cells or accumulators, especially since the amplifier has a low static current.

The device is especially recommended in portable audio equipment.

Selected parameters:

• output power <3 W (depends on the power and resistance of the loudspeaker)
• voltage gain - 40 dB
• frequency response - 20 Hz - 20 kHz
• harmonic distortion - type 0.25% (for Pwy - 0.5 W)
• quiescent current - type 5 mA
• power supply - 3 - 18 V
• in the set a printed circuit board, a set of elements and documentation
