7. Output is noisy with >10kHz inputs.
 This is a fundamental characteristic of this topol-
ogy. The LTC1966 is designed to work very well
with inputs of 1kHz or less. It works okay as high
as 1MHz, but it is limited by aliased S noise.
Solution: Bandwidth limit the input or digitally filter
the resulting output.
8. Large errors occur at crest factors approaching, but
less than 4.
   Insufficient averaging.
Solution: Increase C
AVE
. See Crest Factor and AC + DC
Waveforms section for discussion of output droop.
9. Screwy results, errors > spec limits, typically 1% to 5%.
   High impedance (85k? and high accuracy (0.1%)
  require clean boards! Flux residue, finger grime, etc.
  all wreak havoc at this level.
Solution: Wash the board.
Helpful Hint: Sensitivity to leakages can be reduced
significantly through the use of guard traces.

10. Gain is low by E1% or more, no other problems.
 Probably due to circuit loading. With a DMM or
a 10?scope probe, Z
IN
 = 10M? The LTC1966
output is 85k? resulting in 0.85% gain error.
Output impedance is higher with the DC accurate
post filter.
  Solution: Remove the shunt loading or buffer the
output.
 Loading can also be caused by cheap averaging
capacitors.
  Solution: Use a high quality metal film capacitor
