MAX7414CPA
数据手册.pdf5阶,低通,开关电容滤波器 5th-Order, Lowpass, Switched-Capacitor Filters
General Description
The MAX7409/MAX7410/MAX7413/MAX7414 5th-order, lowpass, switched-capacitor filters SCFs operate from a single +5V MAX7409/MAX7410 or +3V MAX7413/MAX7414 supply. These devices draw only 1.2mA of supply current and allow corner frequencies from 1Hz to 15kHz, making them ideal for low-power post-DAC filtering and anti-aliasing applications. They feature a shutdown mode, which reduces the supply current to 0.2µA.
