LTC1563-2IGN#PBF

The LTC1563-2IGN#PBF is an extremely easy-to-use active RC, 4th Order Low-pass Filter 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 unity-gain Butterworth response. The LTC1563-3, with a single resistor value, gives unity-gain Bessel response. The proprietary architecture of these parts allows for a simple resistor calculation - R = 10k (256kHz/fC), fC = cut-off 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.
