19-4764; Rev 2; 6/99 8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters General Description The MAX7400/MAX7403/MAX7404/MAX7407 8th-order, lowpass, elliptic, switched-capacitor filters (SCFs) operate from a single +5V (MAX7400/MAX7403) or +3V (MAX7404/MAX7407) supply. These devices draw 2mA of supply current and allow corner frequencies from 1Hz to 10kHz, making them ideal for low-power antialiasing and post-DAC filtering applications. They feature a shutdown mode that reduces the 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. In addition, an offset adjustment pin (OS) allows for the adjustment of the DC output level.
