Features

AI Translation
  • 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.
  • Higher order filters can easily be created by cascading multiple MAX7490/MAX7491s.
  • Two clocking options are available: self-clocking (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.
  • 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.
  • 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
  • Internal Sampling-to-Center Frequency Ratio of 200:1
  • Center Frequency up to 40kHz
  • Easily Cascaded for Multipole Filters
  • Low-Power Shutdown: <1μA Supply Current
