The LTC1563-2/LTC1563-3 are a family of extremely easy-to-use, active RC lowpass filters with rail-to-rail inputs and outputs and low DC offset suitable for systems with a resolution of up to 16 bits. The LTC1563-2, with a single resistor value, gives a unity-gain Butterworth response. The LTC1563-3, with a single resistor value, gives a unity-gain Bessel response. The proprietary architecture of these parts allows for a simple resistor calculation:
R = 10k (256kHz/fC); fC = Cutoff Frequency
where fC is the desired cutoff frequency. For many applications, this formula is all that is needed to design a filter. By simply utilizing different valued resistors, gain and other responses are achieved.
The LTC1563-X features a low power mode, for the lower frequency applications, where the supply current is reduced by an order of magnitude and a near zero power shutdown mode.
The LTC1563-Xs are available in the narrow SSOP-16 package (Same footprint as an SO-8 package).
Applications
- Discrete RC Active Filters and Modules
- Antialiasing Filters
- Smoothing or Reconstruction Filters
- Linear Phase Filtering for Data Communication
- Phase Locked Loops

Evaluation Kits 2
DC338B-A
LTC1563-2CGN Demo Board | Universal Lowpass Filter
Product Detail
Demonstration circuit DC338B-A is for the evaluation of filter circuits using an LTC1563-2 and DC338B-B for an LTC1563-3. LTC1563-2 and LTC1563-3 are dual 2nd order active RC filter building blocks with precision ±1.5% capacitors. The LTC1563-2 uses six equal value resistors to implement a 4th order Butterworth lowpass filter, and the LTC1563-3 uses six equal value resistors to implement a 4th order Bessel lowpass filter. The lowpass cutoff frequency (f C ) range of an LTC1563-X filter is 256Hz to 256kHz.
