Despite the relatively small power output specified in the title of the article, it has one distinct advantage – the acoustics can be connected directly to pins – no extra coils is not required – as they say – all included.
Features chips as follows :
| Supply voltage, |
:10 … 22V |
| Supply current absence of a signal, mA | :20mA |
| Maximum Power Output: | |
| in stereo (CG = 10%) | :29W |
| in mono (CG = 10%) | :50W |
| “Normal” Power Output: | |
| in stereo (CG = 0.1%) | :12W |
| in mono (CG = 0.09%) | :22W |
| S / N ratio (weighted) | :96% |
| Efficiency (max) | :87% |
The device has built-in overload protection, output current limiting, suppression of the “click-and-pop” when you turn on and off. There is also a programmable gain amplifier and switch-off temperature.
As can be seen, the device is connected to two power supplies – 22 V – for analog and digital 5-12V. If it is assumed that the chip will be powered by 12 volts, the findings for the power supply can be combined. Otherwise, it is enough to feed the analog part to connect any integral stabilizer – TIPPING or LM.
