Can you e-mail a .pdf to me, I'll try to have a look at it.

Recommendations for op-amps? There are hundreds of them, and each
has it's place. If you're looking at LTC data sheets from '93, you're
probably looking at some kind of precision circuit.. maybe with some
parameters I could make some recommendations. I use about 10 different
types regularly depending on the bandwidth, power consumption, Vos,
TCVos, cost, slew rate, comon mode (single supply, dual supply,
rail-to-rail) and output (power, normal, rail-to-rail) and power
supply voltage (some will operate from +/-15V reliably, others have a
maximum supply voltage of only 5.5VDC.
