功能描述

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).

特点

Extremely Easy to UseA Single Resistor Value Sets the Cutoff Frequency (256Hz < fC < 256kHz)

Extremely FlexibleDifferent Resistor Values Allow Arbitrary Transfer Functions with or without Gain (256Hz < fC<256kHz)

Supports Cutoff Frequencies Up to 360kHz Using FilterCAD?
