I have 2181LC chips. I checked their data sheets (after I bought them, duh) and found the maximumTHD rating so much higher than other types:
2181LC=0.02%
2181LA=0.005%
Are they worthless in this design?
Its all relative. If you check they probably have a better spec than the original 2151 chips, which several people here have used & been more than happy with.
