The LTC1564IG#PBF is a Continuous Time Filter for antialiasing, reconstruction and other band-limiting applications. 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 (fC) and gain are programmable while the shape of the lowpass response is fixed. A latching digital interface stores fC and gain settings or it can be bypassed for control directly from the pins. The LTC1564 operates from 2.7 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 fC (a de-facto standard for DSP front ends).
