Description

A single channel, programmable digital filter designed for seamless insertion in the serial data path of a digital signal or used as an FIR

coprocessor. A circuit example below shows the QF1D512 operating between an ADC and an MCU. The device can be programmed

using the Quickfilter Design Software which supports most FIR digital filter configurations. The FIR filter has 512 taps capable of

generating “brick wall” filters such as a low pass filter with a 1 kHz cutoff frequency, 140dB of rejection, and a total transition band of

only 10 Hz. The filter can operate over a broad range of ADC data rates – from 10sps up to 500ksps and can support ADC’s with

resolutions ranging from 12 to 24 bits.
