TDA7294 100W Audio Amplifier
5.1 amplifier assembling 7294 IC 5 - channel Amplifier Board 5.1 Home Theater !
TDA7294 is an incorporated, solid, Class AB sound intensifier planned explicitly for Hi-Fi applications. The IC has a DMOS yield arrange and can convey 100W RMS into a 8Ohm speaker at +/ - 38V double stock. The TDA7294 has low clamor, low contortion, great wave dismissal and can be worked from a wide scope of supply voltages. The IC has underlying short out security and warm closure hardware. The IC is accessible in multiwatt 15V and multiwatt 15H bundles.

Notes.
TDA7294 Ic Stereo Amplifier IC Powerful Board :
voltage range is Information voltage power supply 24 0 24 v to 28 - 0 -28 DC
Maximum most extreme working voltage 30 0 30 v DC
Yous the Transformer 10 Amp
This TDA7294 Ic Will Work Only On Dual Power Supply DC Input
Speaker best driving 6 inch, 8 ohm for channel 150w + 150w speaker as the load
Speaker best driving 8 inch, 8 ohm for channel 150w + 150w speaker as the load
For 100W yield the stock voltage should be +/ - 38VDC.
The force supply should be all around sifted and liberated from swells.
In case swells are available in the force supply it might cause motions.
VM = 1.5V is the quiet ON limit and VM=3.5V is the quiet OFF edge.
VSTBY = 1.5V is the reserve on edge and VSTBY = 3.5V is the backup OFF edge.
Normal info opposition of TDA7294 is 100KiloOhm.
Recurrence reaction is 20Hz to 20KHz.
145 degree Celsius is the limit for warm closure. Slew pace of TDA7294 is 10V/microsecond and the open circle voltage acquire is 80 dB.
Calm current of TDA7294 is around 30mA and its greatest worth is 65mA.
Description.
In the circuit TDA7294 is designed to give 100W yield power into a 8Ohm amplifier at +/ - 38V stockpile. C8 is the info coupling capacitor and the information is applied to the non-reversing input (Pin3) of the IC. C3 and C9 are power supply channel capacitors while C10 and C4 are sidestep capacitors. C2 is the bootstrap capacitor. RC network involving R1 and C1 further develops the high recurrence security of the speaker and furthermore forestalls motions. R2 and C6 sets the quiet time steady while R3 and C5 sets the backup time consistent. S1 and the quiet switch and S2 are the backup switch. R5 is the info obstruction and the intensifiers input impedance has an immediate relationship to its worth. R4 and R6 is utilized for setting type shut circle acquire and with the pre-owned worth, acquire is 30dB. C2 is a criticism capacitor and it likewise gives DC decoupling.
