MAX7408EPA

5阶，低通，椭圆，开关电容滤波器 5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

General Description

The MAX7408/MAX7411/MAX7412/MAX7415 5th-order, lowpass, elliptic, switched-capacitor filters SCFs operate from a single +5V MAX7408/MAX7411 or +3V MAX7412/MAX7415 supply. The 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 can be put into a low-power mode, reducing supply current to 0.2µA.
