Typical Application for LTC1564 10 to 150 kHz Digitally Controlled Antialiasing Filter

Typical Application for the LTC1564 is a new type of 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
