7.Output is noisy with >50kHz inputs.
 This is a fundamental characteristic of this topol-
ogy. The LTC1967 is designed to work very well
with inputs of 20kHz or less. It works okay as high
as1MHz, but it is limited by aliased ?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 (50k&) and high accuracy (0.1%)
require clean boards! Flux residue, finger grime, etc.
all wreak havoc at this level.
Solution: Wash the board.
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 LTC1967
output is 50k&, resulting in 0.5% 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
for C
