PCB for audio amplifier with TDA7250!

[radio]

Hello friends!
I need a PCB for the amp with TDA7250?
thanks and cheers

You could use the LME49811 instead. It is similar to the TDA7250. The datasheet from National Semiconductor has a PCB layout.

Hi
I have all the components for the TDA7250 amplifier with output transistors 2SC5200/2SA1943!
Otherwise, this circuit is much LME49811 expensive and difficult to be located?
thanks

You can get the datasheet for the LME49811 here:

LME49811 - High Fidelity 200 Volt Power Amplifier Input Stage with Shutdown

In my part of the world the LME49811 is available as a special order, for delivery within a week, for about US$10. It should work with 2SC5200/2SA1943 output transistors.

ampslab sell such a pcb, in fact the schematic you posted is from the ampslab.com website

Hi Jaycee!
Neither can we understand ... I need the TOP PCB layuout (See picture above!)!
Regards!

Here is the web page.

As opposed to discrete designs, the IA502 uses an IC to drive the power stages.

The entire power amplifier circuitry for 2-channels are squeezed into a tiny TDA7250 10-pin IC. All that's required are four power darlingtons and some passive components to complete a high performance stereo amplifier. No biasing is required as the IC auto biases the output transistors.

The IA502 lends itself well to multi-channel amplification.
A 6~8 channel power amplifier can easily be constructed even by beginners.

You will have to ask them about the price for the PCB as it is not listed.

You will need different transisors for their board. The circuit is a little different from yours.

Thanks Ingenieus!
I need PCB (Figure not Picture) for stereo amplifier with TDA7250 with output transistors 2SC5200/2SA1943, not Darligton transistors!
(See schematic above)

Friends, for this picture to need PCB!
thanks
