Good day to all. I'm on yet another project with analog bits inside and none of my=20 favorite dual op-amps are suitable. The LM358 would be perfect, except its output isn't rail-to-rail. I=20 need that in this project. Supply voltage is 5 Vdc. Input must include ground (0V) within the=20 common-mode range but maximum input is about 1.2V. Output needs to=20 swing from about Vss to Vdd, give or take a hundred mV. GBW about 1=20 MHz is fine. It's going to be used in a constant-current sink for battery=20 testing. Input reference varies from 0V to 1.2V - this sets the=20 value of the current being sunk. The output of the op-amp is driving=20 a decent-sized MOSFET through a 100R resistor. Thus, the op-amp has=20 to be stable driving a capacitive load. I want cheap and cheery and have been looking at Microchip's=20 offerings. Alas - there are thousands to choose from and the=20 Microchip parametric search engine has gone from awful to bloody awful. Ideal package for me is SO-8. Does anyone have a favorite part they really like?
