DUAL AMPLIFIER ACTIVE FILTERS (DAAFs)
The LMV822/24 bring economy and performance to DAAFs. The low-pass and the high-pass filters of Figure 41
and Figure 42 (respectively), offer one key feature: excellent sensitivity performance. Good sensitivity is when
deviations in component values cause relatively small deviations in a filter's parameter such as cutoff frequency
(Fc). Single amplifier active filters like the Sallen-Key provide relatively poor sensitivity performance that
sometimes cause problems for high production runs; their parameters are much more likely to deviate out of
specification than a DAAF would. The DAAFs of Figure 41 and Figure 42 are well suited for high volume
production.
