[Three Crystal Electronics Co., Ltd.]

Overview and characteristics
SJ2025 is a two-channel audio power amplifier circuit, the most suitable for multimedia speakers for the left and right channel audio amplifier or bass
(BTL) audio amplifier.

FEATUREs:
   Working voltage range of 3 ~ 13V;
   Its output power:
      Stereo: Po = 2.5W (Typ) at Vcc = 9V, RL = 4Ω
      Bridge: Po = 4.5W (Typ) at Vcc = 9V, RL = 8Ω
   Using double inline 16 feet plastic package (DIP16);
   In addition, it also has less external components, high channel separation, blasting noise less, the voltage gain can be adjusted by external resistors and other features
