SJ2025 circuit


1. The working power supply voltage ranges from 3 to 13V.

2. Its output power is large :
(1) Stereo: Po=2.5W(Typ) at Vcc=9V, RL=4Ω
(2) Bridge type: Po=4.5W(Typ) at Vcc=9V, RL=8Ω

3. Double-in-line 16-pin plastic package (DIP16);

4. In addition, it also has fewer external components, high channel separation, less blasting noise, and voltage gain can be adjusted by external resistors.
