Note 1: Resistive loading of the N_/HP_, LP_, BP_ outputs includes the resistors used for the filter implementation.
Note 2: Crosstalk between internal filter sections is measured by applying a 1VRMS 10kHz signal to one bandpass filter section input
and grounding the input of the other bandpass filter section. The crosstalk is the ratio between the output of the grounded
filter section and the 1VRMS input signal of the other section.
Note 3: Bandwidth of noise measurement is 80kHz.
Note 4: fOSC (kHz) = 135 x 103 / COSC (COSC in pF)
ELECTRICAL CHARACTERISTICS—MAX7491 (continued)
(VDD = VEXTCLK = +3V; fCLK = 625kHz; 10kΩ || 50pF load to VDD/2 at LP_, BP_, and N_/HP_; VSHDN = VDD; 0.1F from COM to
GND; 50% duty-cycle clock input; COM = VDD/2; TA = TMIN to TMAX. Typical values are at TA = +25°C, unless otherwise noted.)
