The MAX7490/MAX7491 consist of two identical low-  
power, low-voltage, wide dynamic range, Rail-to-Rail®,  
2nd-order switched-capacitor building blocks. Each of  
the two filter sections, together with two to four external  
resistors, can generate all standard 2nd-order func -  
tions: bandpass, lowpass, highpass, and notch (band  
reject). Three of these functions are simultaneously  
available. Fourth-order filters can be obtained by cas-  
cading the two 2nd-order filter sections. Similarly, high-  
er order filters can easily be created by cascading  
multiple MAX7490/MAX7491s.  
♦ Dual 2nd-Order Filter in a 16-Pin QSOP Package  
♦ High Accuracy  
Q Accuracy: ±0.2%  
Clock-to-Center Frequency Error: ±0.2%  
♦ Rail-to-Rail Input and Output Operation  
♦ Single-Supply Operation: +5V (MAX7490)  
or +3V (MAX7491)  
♦ Internal or External Clock  
♦ Highpass, Lowpass, Bandpass, and Notch Filters  
♦ Clock-to-Center Frequency Ratio of 100:1  
Two c loc king op tions a re a va ila b le : s e lf-c loc king  
(through the use of an external capacitor) or external  
clocking for tighter cutoff frequency control. The clock-  
to-center frequency ratio is 100:1. Sampling is done at  
twice the clock frequency, further separating the cutoff  
frequency and Nyquist frequency.  
♦ Internal Sampling-to-Center Frequency Ratio  
of 200:1  
♦ Center Frequency up to 40kHz  
The MAX7490/MAX7491 have an internal rail splitter  
that establishes a precise common voltage needed for  
single-supply operation. The MAX7490 operates from a  
single +5V supply and the MAX7491 operates from a  
single +3V supply. Both devices feature a low-power  
shutdown mode and come in a 16-pin QSOP package.  
♦ Easily Cascaded for Multipole Filters  
♦ Low-Power Shutdown: <1µA Supply Current
