The project is based around the hybrid integrated circuit power amplifier with STK4050 manufactured by Sanyo to build a low clatter mono audio amplifier with complete peak quality. Explanation The project has a ceiling output power of 200W while incorporating a volume control. The power supplyused participating in the circuit is an on-board type and as of this, barely a hub tapped transformer is considered necessary in place of the powering of the circuit. The sound has a very fine quality and it can stay proven once used in to your place theaters, in computers, and other audio equipments which can as well be used being subwoofer amplifier. On behalf of water down-type audio sets, it can be considered as a compact package. The leg generated arrived thin-type audio sets is being discrete certainly with a good heatsink design. nearby may possibly live reason someplace a shock din may be encountered especially for the period of switch ON and switch inedible. This can be summary by only if a constant current circuit. The design of the circuit can be tailored used for sinking occurrence of thermal shutdown, brief circuit protection for oodles, shock racket muting from exterior power supply. The load resistance besupposed to arrange 8 Ohms profit with 55K Ohms input impedance.
General description: The TDA8946J is a dual-channel audio power amplifier with an output power of 2 × 15 W at an 8 Ω load and a 18 V supply. The circuit contains two Bridge Tied Load (BTL) amplifiers with an all-NPN output stage and standby/mute logic. The TDA8946J comes in a 17-pin DIL-bent-SIL (DBS) power package. The TDA8946J is printed-circuit board (PCB) compatible with all other types in the TDA894x family. One PCB footprint accommodates both the mono and the stereo products. Features: Few external components Fixed gain Standby and mute mode No on/off switching plops Low standby current High supply voltage ripple rejection Outputs short-circuit protected to ground, supply and across the load Thermally protected Printed-circuit board compatible Circuit Diagram: Circuit Diagram for 2 x 15 W stereo Bridge Tied Load (BTL) audio amplifier PCB layout: PCB layout TDA8946 Datasheet for TDA8946J: Download
