Re: Minimising current in unused op amp

Thanks all of you - I appreciate it..

I've pretty much settled on a LM2904, with:
=94 Input common-mode voltage range includes
negative rail
=94 Differential input voltage range equal to the
power supply voltage
=94 Large output voltage swing 0V to (V
CC+ -1.5V)

Taking into account all your comments, I think I'll turn it into a(n
unnecessary) voltage follower (my op amp is only to scale a voltage
for an A/D conversion).
I'll have the output of the used amp as input into the non-inverting
input, and tie the output of this second amp back to the inverting
input for a unity gain voltage follower with "No extra current draw
involved" (Phil).

Thanks everyone,

Cheers,

Gus
