This circuit consists of two separate 20W bridged power amplifiers (one for
each channel) based on four TDA2003 monolithic Integrated Circuits to
deliver more than 40W of music power into a pair of 4 Ohm speakers.
Running on 12V DC, this stereo amplifier is ideal for the car in order to boost
the audio power or to add two more speakers. In addition, it can be
connected to any stereo audio source such as a Walkman, Discman, or MP3
Player.
Supply voltage: 12 to 18V
DC / 3 to 4A
Based on four TDA2003
Integrated Circuits
Input sensitivity: 100mV /
47K Ohm
Output power using 18V DC
supply:
Music power: > 2 x 22W /
4 Ohm
RMS power: 2 x 16W / 4
Ohm or 2 x 12W / 8 Ohm
Frequency response: 30Hz
to 20KHz (-3dB)
Includes four gold-anodized
heat sinks
Includes volume control
