MAXIM INTEGRATED PRODUCTS  MAX7414CUA+  开关电容滤波器, Butterworth, 低通, 5th, 1, 2.7 V, 3.6 V, µMAX

The is a 5th order low pass, switched capacitor filter in 8 pin µMAX package. This butterworth filters provides a maximally flat pass band response. It operates with a 100:1 clock to corner frequency ratio. The device draw only 1.2mA of supply current and allow corner frequencies from 1Hz to 15KHz, making it ideal for low power post-DAC filtering and anti-aliasing applications. Two clocking options are available on this device, self-clocking through the use of an external capacitor or external clocking for tighter corner-frequency control. An offset adjust pin allows for adjustment of the DC output level. It is used in DAC post filtering, air-bag electronics and CT2 base stations.
