The MAX7409 / MAX7410 / MAX7413 / MAX7414 5th-order, lowpass, switched-capacitor filters (SCFs) operate from a single +5 V (MAX7409 / MAX7410) or +3 V (MAX7413 / MAX7414) supply.

These devices draw only 1.2 mA of supply current and allow corner frequencies from 1...15 kHz, making them ideal for low-power post-DAC filtering and anti-aliasing applications. They feature a shutdown mode, which reduces the supply current to 0.2 µA.

Two clocking options are available on these devices: 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 MAX7409 / MAX7413 Bessel filters provide low overshoot and fast settling, while the MAX7410 / MAX7414 Butterworth filters provide a maximally flat passband response. Their fixed response simplifies the design task to selecting a clock frequency.
