MAX7423EUA-MAX7424EUA-MAX7425CUA
5th-Order, Lowpass, Switched-Capacitor Filters
General Description
The MAX7418–MAX7425 5th-order, low-pass, switched-
capacitor filters (SCFs) operate from a single +5V
(MAX7418–MAX7421) or +3V (MAX7422–MAX7425)
supply. These devices draw only 3mA of supply current
and allow corner frequencies from 1Hz to 45kHz, mak-
ing them ideal for low-power post-DAC filtering and anti-
aliasing applications. They feature a shutdown mode
that reduces supply current to 0.2µA.
Two clocking options are available: self-clocking
(through the use of an external capacitor), or external
clocking for tighter corner-frequency control. An offset
adjust pin allows for adjustment of the DC output level.
The MAX7418/MAX7422 deliver 53dB of stopband
rejection and a sharp rolloff with a 1.6 transition ratio.
The MAX7421/MAX7425 achieve a sharper rolloff with a
1.25 transition ratio while still providing 37dB of stop-
band rejection. The MAX7419/MAX7423 Bessel filters
provide low overshoot and fast settling, and the
MAX7420/MAX7424 Butterworth filters provide a maxi-
mally flat passband response. Their fixed response sim-
plifies the design task of selecting a clock frequency.

Note 1:The maximum fCis defined as the clock frequency fCLK= 100 x fCat which the peak S / (THD+N) drops to 68dB with a
sinusoidal input at 0.2fC. Maximum fC increases as VINsignal amplitude decreases.
Note 2:DC insertion gain is defined as ∆VOUT / ∆VIN.
Note 3:MAX7418/MAX7421/MAX7422/MAX7425: fOSC(kHz) ≅ 87x103/ COSC(pF).
MAX7419/MAX7420/MAX7423/MAX7424: fOSC(kHz) ≅ 110x103/ COSC(pF).
Note 4:PSRR is the change in output voltage from a VDDof 4.5V and a VDDof 5.5V.
