Hi

I am looking for some alternate to LM358.
I want to use it as an integrator to generate a linear ramp 0-32V (actually 0-30V).
LM358's maximum supply voltage is 32V, and the output is 0-28V.
I need output up to 32V or at least 30V.

p.'s, The alternate part should not be expensive, please.

You might have trouble finding a cheap one because of the common mode input range of most op amps being less than the supply voltage you need one that does include the supply. I'll have a look for you.

Yes, LT1490A is quite expensive.
Microchip's maximum supply voltage is 16V (as per data shown on their website).

Unfortunately I think you are going to have to pay a bit more for the op-amp unless you can run the opamp from a slightly higher voltage and then you could go for a standard type. I have had a look quickly on the major players and they all seem to be between £1.50 and the £2.00 mark.

I found two other, MC1556 and MC1558.
