dual BTL 14 watt audio amplifier circuit Datasheet for AN7176: Download

This is a very simple cable TV amplifier using two transistors. This amplifier circuit is most suitable for cable TV systems using 75 Ohm coaxial cables and works fine up to 150MHz. Transistor T1 performs the job of amplification. Up to 20dB gain can be expected from the circuit.T2 is wired as an emitter follower to increase current gain. assembled on a Vero board. Use 12V DC for powering the circuit. Type no of the transistors are not very critical. Any medium power NPN RF transistors can be used in place of T1 and T2. This is just an elementary circuit. Do not compare it with high quality Cable TV amplifiers available in the market.

Amplifier circuit here is all based on the ic in the gains. Three IC TA7230P, TA7236P, TA7237AP is intregated circuit (IC) which was applied to the power amplifier. Each IC has a different output, different input voltage, all IC TA7230P, TA7236P, TA7237AP is manufactured by Toshiba. You can see maximum minimum voltage , power output , and other here TA7230P, TA7236P, TA7237AP amplifier schematic

Here i share power amplifier based on IC TDA7236 . This amplifier require minimum voltage 0,9 volt and maximum voltage is 1, 6 volt , its very low voltage amplifier. You can use this amplifier everywhere just with one battery 1,5 volt. Power output 16 mW with 32 ohms impedance. see circut below :

In this amplifier circuit using IC TDA8944J as the main amplifier with dual-channel audio amplifier with 2 x 7W output power at 8 Ω impedance. And a minimum supply voltage of 9-18 Volts. In this ic contains two Bridge Tied Load or BTL amplifier. The circuit is often found in audio amplifier in a series of television, besides TDA2003, TDA2006 and so forth. PCB for a series of amplifiers using IC TDA8944J is very compatible with all other types of IC in IC TDA894X family unit , and below is a schematics.

This amplifier circuit or with it based on ic KA2210 main amplifier, audio amplifier circuit should disupplay minimum of 10 Volt and up to 16 volts. Power output is 2 x 5.5 W stereo amplifier att. By using this amplifier you can listen to the strains of songs from mp3 player, iPod, etc. This is schematic diagram Part List R1 = 4.7R R2 = 4.7R C1 = 1uF C2 = 100uF C3 = 47uF C4 = 100uF C5 = 0.1uF C6 = 1000uF C7 = 1uF C8 = 100uF C9 = 47uF C10 = 100uF C11 = 0.1uF C12 = 1000uF IC = KA2210
