No other analog components or filter expertise are needed to use it. There is one analog input pin and one analog output pin. The cutoff frequency (f C ) and gain are programmable while the shape of the lowpass response is fixed. A latching digital interface stores f C and gain settings or it can be bypassed for control directly from the pins. The LTC1564 operates from 2.7V to 10V total (single or split supplies) and comes in a 16-pin surface mount SSOP.The LTC1564 is a rail-to-rail high resolution 8th-order lowpass filter with two stopband notches, giving approximately 100dB attenuation at 2.5 times the passband cutoff frequency f C (a de-facto standard for DSP front ends). Signals with low or variable levels can be normalized with the built-in variable gain that reduces input-referred noise with increasing gain for a typical dynamic range (maximum signal level to minimum noise) of 122dB (20 equivalent bits) with 20kHz f C and 118dB at 100kHz f C on a ±5V supply.Other frequency-response shapes can be provided upon request.
