Overview

5th-Order, Elliptic Lowpass Filters
Low Noise and Distortion: -80dB THD + Noise
Clock-Tunable Corner Frequency (1Hz to 15kHz)
Single-Supply Operation
- +5V (MAX7408/MAX7411)
- +3V (MAX7412/MAX7415)
Low Power
- 1.2mA (operating mode)
- 0.2µA (shutdown mode)
Available in 8-Pin µMAX®/DIP Packages
Low Output Offset: ±4mV

The MAX7408/MAX7411/MAX7412/MAX7415 5th-order, lowpass, elliptic, switched-capacitor filters (SCFs) operate from a single +5V (MAX7408/MAX7411) or +3V (MAX7412/MAX7415) supply. The devices draw only 1.2mA of supply current and allow corner frequencies from 1Hz to 15kHz, making them ideal for low-power post-DAC filtering and anti-aliasing applications. They can be put into a low-power mode, reducing supply current to 0.2µA.

Two clocking options are available: self-clocking (through the use of an external capacitor) or external clocking for tighter cutoff-frequency control. An offset-adjust pin allows for adjustment of the DC output level.

The MAX7408/MAX7412 deliver 53dB of stopband rejection and a sharp rolloff with a transition ratio of 1.6. The MAX7411/MAX7415 achieve a sharper rolloff with a transition ratio of 1.25 while still providing 37dB of stop-band rejection. Their fixed response limits the design task to selecting a clock frequency.
