This amplifier circuit based MAX9751 IC which work on the 5 Volt voltage, unipolar, and a 2.6 Watt power output per channel. In addition, there is a headphone output with separate amplifier and the input selector inputs – you can connect two sources of signal.
|Supply voltage||: 4,5V-5,5V|
|Supply current absence of a signal||: 14mA|
|Output power (max)||: 2.6W|
|THD (P = 1W, RL = 4 Ohm)||: 0.02%|
|S / N ratio||: 90dB|
A few more words on the chip. This is a bridge amplifier class AB integrated into the protection against overheating, short circuit protected outputs, suppression of inrush current when you turn on and off the amplifier.
Parts list :
|S1||Anyone with a fixation|
|XS1||Headphone jack – depends on the headphones|
