Circuit Amplifier MosFet 25 Watt
25 Watt power amplifier based MosFet, can be connected directly to the signal source and does not require pre-amplifier to drive.
The amplitude of the input signal must reach the level of 200 mV. This signal is normally present on the linear output recorder, CD player, computer sound card and other devices.
To adjust the volume can be placed at the entrance to the potentiometer 10 kohm. Trimmer adjustable quiescent current. It must be within 100 mA.
Output power : well in excess of 25 Watt RMS @ 8 Ohm (1KHz sine wave)
Sensitivity : 200mV input for 25W output
Frequency response : 30Hz to 20KHz -1dB
Total harmonic distortion @ 1KHz : 0.1W 0.014% 1W 0.006% 10W 0.006% 20W 0.007% 25W 0.01%
Total harmonic distortion @10KHz : 0.1W 0.024% 1W 0.016% 10W 0.02% 20W 0.045% 25W 0.07%
Unconditionally stable on capacitive loads
