Description

The LTC®1563-2/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.
