so let me get this right.
Theres a slight power difference in one Tda2003 to another even though there the same.
but with a 8pin dual amp would work better cause there together in one IC.

The TDA2003 does not bridge well because the output offset voltage are not matched for the two amplifiers like a monolithic bridged amplifier IC. But you might be lucky so try it.

With a 14.4V supply the bridged output at clipping into 4 ohms is 14 watts.
If your speakers are 8 ohms then the power is 8 Watts.
If the supply voltage is less than 14.4V then the power is less.

You should make an active crossover circuit.

I'm having a real hard time with these!
Here is what I have so far. These only mention your chips but, it is something.

Looking for an Ultrasonic Cleaner  schematic.

Darrin,

Can this help you?

Ante ::)

I read several datasheets and application notes on 555 timers, but I can't seem to find the information I'm looking for.

Specifically, I'd like to use the 555 as a pulse width modulator by using the control voltage (pin 5). The datasheets indicate that in monostable mode, the output pulse width can be varied by modulating the voltage at pin 5 (V5). They also indicate that in astable mode, modulating V5 will modulate pulse position.

What I'm wondering is this: What is the relationship between the control voltage, V5, and the values of the timing resistors and caps? There are standard formulas for timing based on these resistors and caps. How are those formulas affected by the introduction of V5?


Thanks.

Darrin

A schematic would help us to answer the question.
I wouldn't recommend either. A MOSFET would probably be better.

Good evening to everyone.
Is it ok to use TIP 120 instead of TIP 122?
Thanks in advance
