ELECTRICAL CHARACTERISTICS—MAX7427 (continued)
(VDD = +3V, filter output measured at OUT pin, 10k
|| 50pF load to GND at OUT, SHDN = VDD, OS = COM, 0.1F from COM to
GND, fCLK = 100kHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
ELLIPTIC FILTER CHARACTERISTICS (r = 1.25)
(VDD = +5V for MAX7426, VDD = +3V for MAX7427, filter output measured at OUT, 10k
|| 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.) (Note 3)
Note 1: The maximum fC is defined as the clock frequency fCLK = 100 fC at which the peak SINAD drops to 68dB with a sinu-
soidal input at 0.2fC.
Note 2: DC insertion gain is defined as
VOUT / VIN.
Note 3: fOSC (kHz)
≈ 17.5 103 / COSC (COSC in pF).
Note 4: The input frequencies, fIN, are selected at the peaks and troughs of the ideal elliptic frequency responses.
fIN = 0.68fC
fIN = 0.38fC
fIN = 3.25fC
fIN = 1.43fC
fIN = 1.25fC
fIN = 0.87fC
fIN = 0.97fC
fIN = fC
