8th-Order, Lowpass,
Switched-Capacitor Filters
order continuous lowpass filter. This filter is convenient for
anti-aliasing applications, or for clock noise attenuation at
the switched-capacitor filter’s output. Figure 4 shows a
2nd-order lowpass Butterworth filter built using the
uncommitted op amp with a 10kHz corner frequency.
This filter’s input resistance of 22k satisfies the minimum
load requirements of the switched-capacitor filter.
The uncommitted op amp (with a 2MHz gain bandwidth
product) can alternatively be used at the input of the
switched-capacitor filter to help reduce any possible
clock ripple feedthrough to the output.
DAC Post-Filtering
When using the MAX291/MAX292/MAX295/MAX296 for
DAC post-filtering, synchronize the DAC and the filter
clocks. If clocks are not synchronized, beat frequen-
cies will alias into the desired passband. The DAC’s
clock should be generated by dividing down the
switched-capacitor filter’s clock.
Harmonic Distortion
Harmonic distortion arises from nonlinearities within the
filters. These nonlinearities generate harmonics when a
pure sine wave is applied to the filter input. Table 2 lists
typical harmonic distortion values for the MAX291/
MAX292/MAX295/MAX296 with a 1kHz 5Vp-p sine-wave
input signal, a 1MHz clock frequency, and a 5k
load.
