The LTC1562CG#PBF is a low noise/distortion active rc quad Universal Filter with rail-to-rail inputs and outputs, optimized for a center frequency (fO) of 10 to 150kHz. 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 center frequency, Q and gain, using simple design formulas. Each 2nd order block provides lowpass and bandpass outputs. Highpass response is available if an external capacitor replaces one of the resistors. Allpass, notch and elliptic responses can also be realized. The LTC1562 is designed for applications where dynamic range is important. Varying the gain of a section can achieve a dynamic range as high as 118dB with a ±5V supply.
