MAX7401EPA+

MAXIM INTEGRATED PRODUCTS  MAX7401EPA+  开关电容滤波器, Bessel, 低通, 8th, 1, 4.5 V, 5.5 V, DIP

The is a 8th order low pass bessel switched capacitor filter SFC in 8 pin DIP package. This device draw only draw only 2mA of supply current and in shutdown mode, the supply current reduce to 0.2µA. When using the MAX7401 for anti-aliasing or post DAC filtering, synchronize the DAC and the filter clocks. If the clocks are not synchronized, beat frequencies may alias into the pass band. A high clock to corner frequency ratio allows a simple RC low pass filter with the cut-off frequency set above the SCF corner frequency to provide input anti-aliasing and reasonable output clock attenuation.
