LTC1562-2  
Very Low Noise, Low Distortion  
Active RC Quad Universal Filter

FEATURES  
DESCRIPTIO  
The LTC®1562-2 is a low noise, low distortion continuous  
time filter with rail-to-rail inputs and outputs, optimized for a  
center frequency (fO) of 20kHz to 300kHz. 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 out-  
puts. Highpass response is available if an external capacitor  
replaces one of the resistors. Allpass, notch and elliptic  
responses can also be realized.

The LTC1562-2 is designed for applications where dynamic  
range is important. For example, by cascading 2nd order  
sections in pairs, the user can configure the IC as a dual 4th  
order Butterworth lowpass filter with 90dB signal-to-noise  
ratio from a single 5V power supply. Low level signals can  
exploit the built-in gain capability of the LTC1562-2. Varying  
the gain of a section can achieve a dynamic range as high as  
114dB with a ±5V supply.
