hello sir
can i put 0.1 micro farad between pin no.5 and pin no.6 of ic ir2110 because there is not space at my pcb.thanks masood

there are many packages of a smaller size , or use smt package under the board

Hello Guys


Nobody want give or share PCB files for supplier, often same with schematic, people make big secret

Detex Audio Thailand dont sell IRS amplifier Boards to me and friends,
he say, dont sell for foreigner and Thai People have foreigner friends,
crazy this guy !

I get angry this week and design AUD600 PCB by myself !
I accept to share files for PCB supplier and schematics with other DIY

Only manojtm share AUD600 schematic with me....

Have design double Layer PCB for AUD600
- add DC protect Crowbar (thanks to APEX)
- add Led for Power - Signal and Clip (thanks to APEX)


Attachments:

AUD600 PCB IRFP4768 Mosfet with Crowbar and LED Power - Signal - CLIP

AUD600 PCB with 2 x IRFP4768 Mosfets with totem pole driver, Crowbar DC protect and LED Power - Signal - CLIP

Hi,

except spectrum all i need (sub(frq adj & Q adj)+bass+mid+treble+balance+fader+input select etc.. LCD with encoder

Regards
MANOJ

for lcd driver use FT800
it is very fast for drive lcd
for adc you can use texas product
it is very good for audio

I give you all bonus, UcD200, with PCB this time.

Hello. What kind of diode can I replace with 31GF6?

Hi I hope all is well. Can anyone share PCB of this Class D amp... I would like to build this with 200W 8Ohm power. I really appreciate help Thanks in advance!!

 

[Wasim]

Hi Can I have IR900D PCB and Diagram I really want to build this amp. Plz also guide me will it work fine on 70 0 70 VDCrail? Thanks in advance!!

 

[masood251]

How is this

 

[masood251]

I get this image by my friend zubair .can i use mosfet 60n60 thanks

 

[masood251]

In this circuit i get 5.9v dc at out put please help me

Hi
how are you today ?
i need a digital class D amp
i seen before class D amp with TL074 opamp here
i need a working schematic or pcb without error for it
i need it with OCP and DC and short circuit protection
any one can help please ?
thank you

oh my god
very very active page

schematic please !

only PCB layout impossibile to help

Some months ago I did finish a class D amp, a fase shift frequency doubling type, it give very low distortion in sim, with deadtime active, output is 8 amps in 8 ohms full bridge output,.

So with good parts and a very fast integrator, comparator and mosfets class D can be high end.

Do build it in future to see, now first the allfet circlotron, who is a lineair amp.

regards

please share schematic !!!

Two different 900w amplifier operation. Different circuits from each. I have copied the pcb to the other's scheme but I don't have both at the moment. No plugs. No current draw. Integrations are intact. I wonder what could be the problem? The material on the circuit without schema was deleted. I hope the cd4070 is right.

check signel input non inverted and inverted ,,,ok

,,,add 1k 3w for each amp speaker out and gnd0 .

I do not have an Osilaskop .. Normally I am testing the Ir2110 output with hi side and low side on the internet circuit. I've changed the integration again, not very interesting. I put a serial 220 volt lamp between the transformer and the mosfet.
