MAX7427是Maxim美信半导体公司的一款滤波器(连续模式和开关电容)产品,MAX7427是五阶、低通、椭圆函数、开关电容滤波器,本站介绍了MAX7427的封装应用图解、特点和优点、功能等,并给出了与MAX7427相关的Maxim元器件型号供参考。
MAX7427 - 五阶、低通、椭圆函数、开关电容滤波器 - 滤波器(连续模式和开关电容) - 业内功耗最低、尺寸最小的5阶低通滤波器 - 美信半导体
The MAX7426/MAX7427 5th-order, lowpass, elliptic, switched-capacitor filters (SCFs) operate from a single +5V (MAX7426) or +3V (MAX7427) supply. The devices draw only 0.8mA of supply current and allow corner frequencies from 1Hz to 12kHz, making them ideal for low-power post-DAC filtering and anti-aliasing applications. They can be put into a low-power mode, reducing supply current to 0.2µA.
Two clocking options are available: self-clocking (through the use of an external capacitor) or external clocking for tighter cutoff-frequency control. An offset-adjust pin allows for adjustment of the DC output level.
The MAX7426/MAX7427 deliver 37dB of stopband rejection and a sharp rolloff with a transition ratio of 1.25. Their fixed response limits the design task to selecting a clock frequency.
