FILTER CHARACTERISTICS
(VDD = +5V, 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.)
Note 1: The maximum fC is defined as the clock frequency fCLK = 100 · fC at which the peak SINAD drops to 68dB with a sinusoidal
input at 0.2fC.
Note 2: DC insertion gain is defined as
∆VOUT / ∆VIN.
Note 3: OS voltages above VDD - 1V saturate the input and result in a 75µA typical input leakage current.
Note 4: fOSC (kHz) ≅ 53 · 103 / COSC (pF).
