[sdiy] Aaron's updated datasheet and ap note archive

Texas Instruments TLC251 TLC27L2 TLC27L4 are jellybean micropower, but 
run on single-supply, max +15V, so don't use with +/-15V. Ten uA per 
amplifier on the chip. Fairly slow (low GBWP and slew rate spec'd in 
V/millisecond), like most low-power op amps. OP290 good for precision 
micropower, but also very slow. All of above can be used with very low 
supply voltages.

Hard to beat the old TL061/TL062/TL064 at 200 uA/amplifier for jellybean 
 low-power applications where reasonable speed is required. 1 MHz GBWP 
and 3.5 V/uS slew rate, puts it between "741 audio performance" and 
"TL084 audio performance". It may be run at +/-15V, also can be run on 
lower voltages than the TL07x and TL08x families.
