My Circuit

This is a circuit of amplifiers are based on the most high-ic power that I have ever known. Because the output is issued up to 1000 watts with the impedance RL 4Ohm. Current supply 120mA, and 30A output current. Minimum input voltage of about 30V and a maximum voltage up to 150V. This is an audio amplifier that I have come across use ICs that maximum voltage up to 150V and output power up to 1000W , the scheme below gan. Part List Resistor R1 = 10K R2 = 10K R3 = 220K R4 = 0.18R 5W R5 = 2.2R 2W R6 = 0.18R 5W Capacitor C1 = 1uF C2 = 1000uF C3 = 68pF C4 = 1000uF Inductor L1 = 4MH IC U1 = PA03

Not all that omplicated circuit schematic of power amplifiers have a good and quality sound, but in the circuit above , although a little tricky for the layman on the circuit , and the sound quality is also good. Technical information : V max  = 16 Vdc V min  = 10 Vdc P out    = 2 x 9,6W R l       = 4 Ohm

This circuit based on IC TDA3000 or you can use IC TDA2870 , minimum voltage require 12 volts and maximum voltage require 35 volts DC. Maximum ouput power 30 Watts mono audio amplifier with 4 Ohm impedance. see below the circuit :

The HA13153A/HA13154A is high output and low distortion 4 ch BTL power IC designed for digital ca raudio. At 13.2 V to 4 Ω load, this power IC provides output power 15 W with 10% distortion. Circuit Diagram: Circuit diagram for 4 x 15 Watt amplifier car audio Datasheet for HA13153: Download

By using the above amplifier circuit you can hear the sound quality is quite good by a high output power. Maximum voltage circuit pa approximately 55Volt DC. 70-140W output power with impedance 8Ohm. Part List R1 = 10K R2 = 1K R3 = 0.4R R4 = 0.4R R5 = 4.7R C1 = 0.015 C2 = 10uF C3 = 220uF C4 = 0.15uF C5 = 220uF C6 = 47uF C7 = 0.047uF U1 = STK050 , STK070

Have you been use the IC above? if those who have not, IC above is used or applied to the audio power amplifier. IC processing is quite good for use on amplifier home, or room. IC used is SI1020G who have not very high output with only 20W 8 ohm impedance speakers. Supply voltage ranging from 12 volt to 23 volts. Below schematic audio amplifier with IC SI1020G Part List R1 = 100K R2 = 1R C1 = 2u2F C2 = 100uF C3 = 47uF C4 = 10uF C5 = 2200uF C6 = 47uF C7 = 100uF 

GENERAL DESCRIPTION The TDA2613 is a hi-fi audio power amplifier encapsulated in a 9-lead SIL plastic power package. The device is especially designed for mains fed applications (e.g. tv and radio). Features Requires very few external components Input muted during power-on and off (no switch-on or switch-off clicks) Low offset voltage between output and ground Hi-fi according to IEC 268 and DIN 45500 Short-circuit-proof Thermally protected.
