MAX7408CUA+T

The MAX7408CUA+T from Maxim Integrated Products is a 5th-order, low pass, elliptic, switched-capacitor filter in 8 pin µMAX package. The device draws only 1.2mA of supply current and allows corner frequencies from 1Hz to 15KHz, making it ideal for low power post DAC filtering and anti-aliasing applications. It can be put into a low power mode, reducing supply current to 0.2µA. This device delivers 53dB of stopband rejection and a sharp roll-off with a transition ratio of 1.6. It has two clocking options like self-clocking (through the use of an external capacitor) or external clocking for tighter corner frequency control. MAX7408 is typically used for post-DAC filtering, speech processing, CT2 base stations and anti-aliasing applications.
