Maxim MAX7408/MAX7411/MAX7412/MAX7415 5th-Order Lowpass Elliptic Switched-Capacitor Filters Datasheet
The document details four models of 5th-order, lowpass, elliptic, switched-capacitor filters (SCFs) designed to operate from a single +5V supply (MAX7408/MAX7411) or +3V supply (MAX7412/MAX7415). These devices are intended for low-power post-DAC filtering and anti-aliasing applications, drawing only 1.2mA of supply current in operating mode and allowing corner frequencies from 1Hz to 15kHz.
The datasheet provides absolute maximum ratings, electrical characteristics including filter response, power requirements, and shutdown specifications. It also includes typical operating circuits, pin configurations, and graphs illustrating frequency response, phase response, supply current versus temperature, and total harmonic distortion plus noise.
