MAX7490/MAX7491 19-1768 Rev 1 4/09 Dual Universal Switched-Capacitor Filters General Description Features The MAX7490/MAX7491 consist of two identical low- Dual 2nd-Order Filter in a 16-Pin QSOP Package power, low-voltage, wide dynamic range, rail-to-rail, High Accuracy 2nd-order switched-capacitor building blocks. Each of Q Accuracy: 0.2% the two filter sections, together with two to four external Clock-to-Center Frequency Error: 0.2% resistors, can generate all standard 2nd-order func- tions: bandpass, lowpass, highpass, and notch (band Rail-to-Rail Input and Output Operation reject). Three of these functions are simultaneously Single-Supply Operation: +5V (MAX7490) available. Fourth-order filters can be obtained by cas- cading the two 2nd-order filter sections. Similarly, high- or +3V (MAX7491) er order filters can easily be created by cascading Internal or External Clock multiple MAX7490/MAX7491s. Highpass, Lowpass, Bandpass, and Notch Filters Two clocking options are available: self-clocking (through the use of an external capacitor) or external Clock-to-Center Frequency Ratio of 100:1 clocking for tighter cutoff frequency control. The clock- Internal Sampling-to-Center Frequency Ratio to-center frequency ratio is 100:1. Sampling is done at of 200:1 twice the clock frequency, further separating the cutoff frequency and Nyquist frequency. Center Frequency up to 40kHz The MAX7490/MAX7491 have an internal rail splitter Easily Cascaded for Multipole Filters that establishes a precise common voltage needed for Low-Power Shutdown: < 1A Supply Current 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.
