TDA1011 2 to 6 W audio power amplifier

Description:

     The TDA1011 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4Ω load impedance. The device can deliver up to 6 W into 4Ω at 16 V loaded supply in mains-fed applications. The maximum permissible supply voltage of 24 V makes this circuit very suitable for d.c. and a.c. apparatus, while the very low applicable supply voltage of 3,6 V permits 6 V applications.

Special features:

• single in-line (SIL) construction for easy mounting
• separated preamplifier and power amplifier
• high output power
• thermal protection
• high input impedance
• low current drain
• limited noise behaviour at radio frequencies

Reference:

• Supply voltage range Vp...........................3,6 to 20 V 
• Repetitive peak output current IORM...........max. 3 A 
• Operating ambient temperature Tamb ........−25 to + 150 °C 
• Storage temperature Tstg ........................−55 to + 150 °C

TDA1010A 2 x 6W audio power amplifier

Description:

     The TDA1010A is a monolithic integrated class-B audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is primarily developed as a 6 W car radio amplifier for use with 4Ωand 2Ωload impedances. The wide supply voltage range and the flexibility of the IC make it an attractive proposition for record players and tape recorders with output powers up to 10 W.

Special features:

• single in-line (SIL) construction for easy mounting 
• separated preamplifier and power amplifier 
• high output power 
• low-cost external components 
• good ripple rejection 
• thermal protection 

Reference:

• Supply voltage range Vp...........................6 to 24 V 
• Repetitive peak output current IORM...........max. 3 A 
• Operating ambient temperature Tamb ........−25 to + 150 °C 
• Storage temperature Tstg ........................−55 to + 150 °C

1000W MOSFET stage Master MK2

1000W MOSFET Description:

Fifth Generation HEXFETs from International Rectifier utilize advanced processing techniques to achieve extremely low on-resistance per silicon area. This benefit, combined with the fast switching speed and ruggedized device design that HEXFET Power MOSFETs are well known for, provides the designer with anextremely efficient and reliable device for use in a wide variety of applications.

The TO-247 package is preferred for comme rcial-industrial applications where higher power levels preclude the use of TO-220 devices. The TO-247 is similar but superior to the earlier TO-218 package because of its isolated mounting hole. The 1000Watt MOSFET LEGEND stage Master MK2 is a very good and powerful amplifier. It is not into the classroom HiEnd sure, but very respectable sounding unit with lots of of power. It was not designed with home interior as the primary goal before, such a power used only rarely in the house and indoor except perhaps in some larger nightclubs. Frankly, due to a high performance, could PA light rather go class, but other specifications and great quality over the PA standards and needs! My only additional suggestion for you to think about it at length, Master internship as a Master MK2.Internship Master 500 ... 1000W, but is aa little easier (and cheaper) to build. "PCB show thus as below 1000W mosfet PCB 1000W mosfet PCB.

100 Watt MOSFET Amplifier Circuit

Circuit Descpription

MOSFET based amplifiers as we all know are outstanding with their sound qualities and they can easilly beat the performance of other counterparts based on power transistors or linear ICs.

However amplifiers based on mosfets are not always easy to design or make.
