MAXIM INTEGRATED / ANALOG DEVICES MAX7400ESA Lowpass Filter

The MAX7400ESA+ is an 8th-order, low-pass elliptic switched capacitor filter housed in an 8-pin NSOIC package. Operating from a single +5V supply, it effectively covers corner frequencies from 1Hz to 10kHz, ideal for low-power anti-aliasing and post-DAC filtering applications. Its features include a shutdown mode reducing power to 0.2µA, two clocking options—self-clocking via an external capacitor or external clock input—for precise cutoff control, and an offset pin for DC level adjustment. With 82dB stopband rejection, a transition ratio of 1.5, low noise (-82dB THD+noise), and a clock-to-frequency ratio of 100:1, it simplifies design by setting the clock frequency. Suitable for ADC anti-aliasing, speech processing, automotive electronics, and telecommunications, it operates over 4.5V to 5.5V and temperatures from -40°C to 85°C, featuring low output offset (+/-5mV) and a clock oscillator frequency of 38kHz.
