MAX7404ESA+T

The MAX7404ESA+T from Maxim Integrated Products is a 8th order, low pass, elliptic, switched capacitor filter in 8 pin NSOIC package. It draws 2mA of supply current and allows corner frequencies from 1Hz to 10KHz making it ideal for low power antialiasing and post DAC filtering applications. It features a shutdown mode that reduces the supply current to 0.2µA. Self-clocking (through the use of an external capacitor) or external clocking for tighter cut-off frequency control are two clocking options available. In addition, an offset adjustment pin (OS) allows for the adjustment of the DC output level. Typical applications include ADC anti-aliasing, post-DAC filtering, CT2 base stations, speech processing and air-bag electronics.
