Amplifier circuit diagram using stk4152:
This is an Amplifier circuit diagram using stk4152. this board can make 30 Watts + 30 Watts. We can use 20-0-20 voltage to 35-0-35 voltage. this is a stereo board. In this circuit, we can use STK 4141 to STK 4191. here need dual voltage. positive negative and ground voltage. Features
The (STK4152) series STK4102 and STK4101V series
(the high-grade type) are pin-consistent in the output range of 6W to 50W and enable easy diagrams.
The Small-sized package whose pin assignment is the same
as that of the STK4101 series
The Built-in muting circuit cut off many kinds of pop noise
The Greatly reduced heat sink due to the substrate temp is 125°C
The best cost performance.
The power dissipation of the STK4152 at the IC-operated mode is 50 Watts max. the load resistance 8Ω and 67W maximum.
the load resistance 4Ω (drive of 2 channels) for continuous sine wave as shown in Figures 1 and 2.
Please use strong voltage. Always use the best quality transformer diode and capacitor to produce good voltage. here needs a minimum 2200uf and 50 voltage capacitor. the diode will be a minimum of 6 amperes. This board doesn’t have any output protection system. so needs speaker protection to protect the speaker. if the IC gets a short circuit then the protection circuit will protect the speaker from being burnt. the protection circuit diagram
