Overview
19-1768; Rev 1; 4/09 Dual Universal Switched-Capacitor Filters MAX7490/MAX7491 General Description The MAX7490/MAX7491 consist of two identical lowpower, 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 functions: bandpass, lowpass, highpass, and notch (band reject).
Three of these functions are simultaneously available.
Fourth-order filters can be obtained by cascading the two 2nd-order filter sections.
Similarly, higher order filters can easily be created by cascading multiple MAX7490/MAX7491s.
Two clocking options are available: s...
