FILTER CHARACTERISTICS
(VDD = +5V for MAX7409/MAX7410, VDD = +3V for MAX7413/MAX7414, filter output measured at OUT, 10kΩ || 50pF load to GND at
OUT, SHDN = VDD, fCLK = 100kHz, TA = TMIN to TMAX, unless otherwise noted.)
Note 1: The maximum fC is defined as the clock frequency fCLK = 100 x fC at which the peak S / (THD+N) drops to 68dB with a
sinusoidal input at 0.2fC.
Note 2: DC insertion gain is defined as
∆VOUT / ∆VIN.
Note 3: fOSC (kHz) ≅ 30 x 103 / COSC (pF).
Note 4: PSRR is the change in output voltage from a VDD of 4.5V and a VDD of 5.5V.
