MAX7480EPA+

The MAX7480EPA+ is an 8th-order, lowpass, butterworth, switched-capacitor filter in 8 pin DIP package. It operates from a single +5V supply. The device draws only 2.9mA of supply current and allows corner frequencies from 1Hz to 2KHz making it ideal for low power post DAC filtering and anti-aliasing applications. The MAX7480 features a shutdown mode which reduces the supply current to 0.2μA. Two clocking options are available: 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. The MAX7480 Butterworth filter provides a maximally flat passband response. The fixed response simplifies the design task to selecting a clock frequency. This device is used in ADC anti-aliasing and post DAC filtering.
