Is there a good op amp selector guide anywhere where you can see all the parameters you want and the price from all the suppliers ?
It always seems to consume so much time looking for the opamp wich has the best specs for the best price, I use Farnell mostly, but if I enter every parameter I need it usualy turns up nothing, so I spend ages looking at datasheets.
For instance I need a better op amp for my PLL loop, it just drives a 30v varactor based vco with usual filter, at the moment im using a lm358, I have loads of them as theyr quite cheap and will do for many situations, however I need to increase the loop bandwidth wich is limited by the 1mhz gbw of the op amp.
requirments :-single supply 30v, low ICC, at least 25mhz gbw, low IIB, short circuit protected, able to drive 100R+1nf series load good PSRR, moderate noise/offset etc. no nasty surprises such as diodes accros the inputs etc.. idealy dual amp in soic8,
It would be good to find one thats good enough to use in as many places as possible and cheap enough to buy in bulk.
