LTC1562-2 is a low noise, low distortion continuous time filter. Unlike most monolithic filters, no clock is needed. Four independent 2nd order filter blocks can be cascaded in any combination, such as one 8th order or two 4th order filters. Each block's response is programmed with three external resistors for centre frequency, Q and gain, using simple design formulas. Each 2nd order block provides low pass and bandpass outputs. High pass response is available if an external capacitor replaces one of the resistors. All pass, notch and elliptic responses can also be realized. It is used in application like high resolution systems (14bits to 18bits), antialiasing/reconstruction filters, data communications, equalizers, dual or I-and-Q channels (two matched 4th order filters in one package), linear phase filtering, replacing LC filter modules etc.
