MAX7480 Datasheet 8th-order / Lowpass / Butterworth / Switched-capacitor Filter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1416; Rev 0; 1/99 8th-Order, Lowpass, Butterworth, Switched-Capacitor.

General Description

The MAX7480 8th-order, lowpass, Butterworth, switched-capacitor filter (SCF) 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.

Key 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. Features o 8th-Order, Lowpass Butterworth Filter o Low Noise and D.
