ELECTRICAL CHARACTERISTICS—MAX7404/MAX7407 (continued)
(VDD = +3V, filter output measured at OUT, 10kΩ || 50pF load to GND at OUT, SHDN = VDD, OS = COM, 0.1µF from COM to GND,
fCLK = 100kHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
ELLIPTIC (r = 1.5) FILTER CHARACTERISTICS—MAX7400/MAX7404
(VDD = +5V for MAX7400, VDD = +3V for MAX7404; filter output measured at OUT; 10kΩ || 50pF load to GND at OUT; SHDN = VDD;
VCOM = VOS = VDD / 2; fCLK = 100kHz; TA = TMIN to TMAX; unless otherwise noted. Typical values are at TA = +25°C.)
VCLK = 0 or 3V
