L lokizwell New Member Mar 11, 2010 #1 I just want to know if, TDA2030A and C4558C is capable of handling about 3 Amps.
Hero999 Banned Mar 11, 2010 #2 Why not look at the data sheets? I know the TDA2030 can handle 3.5A, I've never heard of the C4558C.
L lokizwell New Member Mar 11, 2010 #3 okey,...i seen datasheets for C4558 but i don't know where to find the maximum current condition.... there is some current rating but in the order of nano-amps.....

Hero999 Banned Mar 11, 2010 #4 The C4558 is an operational amplifier. The voltage swing is 25V into a 1k load, with a +/-15V supply, that's 12.5V peak and a current of 12.5mA, as the load resistance is reduced, the voltage swing is also reduced. So no, of course is can't handle 3A.

L lokizwell New Member Mar 12, 2010 #5 oh, gee thanks.......and, uhmmm...do you know a somewhat similar op-amp equivalent to the C4558 that can handle 3 Amp?

Hero999 Banned Mar 12, 2010 #6 The easiest way is to add a power amplifier, which can drive 3A, to the output of the op-amp. What exactly are you doing?

L lokizwell New Member Mar 12, 2010 #7 2.1 channel speakers...using the 3 TDA2030, and well i'm using the C4558 as a pre-amp to one of the TDA2030 for the woofer or bass...is that correct?

Hero999 Banned Mar 12, 2010 #8 Yes, but I'd recommend a better op-amp such as the TL072 or TL074 (quad) over the C4458C.
