MAX7403ESA+

The MAX7403ESA+ is a low-pass elliptic Switched-capacitor Filter for ADC anti-aliasing and air-bag electronics. The 8th-order switched-capacitor filter operate from a single +5V supply. These devices draw 2mA of supply current and allow corner frequencies from 1Hz to 10kHz, making them ideal for low-power anti-aliasing and post-DAC filtering applications. They feature a shutdown mode that reduces the supply current to 0.2µA. The MAX7403 provides a sharper roll off with a transition ratio of 1.2, while still delivering 60dB of stop band rejection. The fixed response of these devices simplifies the design task to corner-frequency selection by setting a clock frequency.
