APPLICATION NOTE 29
Multipurpose Filter Network Combines Anti-Aliasing and Sinc
Compensation


Abstract:In this application note a circuit with two switched-capacitor filters reconstructs the output of a digital-to-analog
converter (DAC) while providing anti-aliasing and sinc-compensation functions. Filter IC prevents alias frequencies by excluding
spectral energy above fs/2. The MAX265 filter is featured.

The dual-biquad filter chips and some external components ( Figure 1) form a multipurpose filter for the reconstruction of D/A
converter signals. Connected to a converter's output ( Figure 2
