LTC1563描述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. The LTC1563-Xs are available in the narrow SSOP-16 package (Same footprint as an SO-8 package).
LTC1563特点Extremely Easy to Use—A Single Resistor Value Sets the Cutoff Frequency (256Hz < fC < 256kHz) Extremely Flexible—Different Resistor Values Allow Arbitrary Transfer Functions with or without Gain (256Hz < fC<256kHz) Supports Cutoff Frequencies Up to 360kHz Using FilterCAD™ LTC1563-2: Unity-Gain Butterworth Response Uses a Single Resistor Value, Different Resistor Values Allow Other Responses with or without Gain LTC1563-3: Unity-Gain Bessel Response Uses a Single Resistor Value, Different Resistor Values Allow Other Responses with or without Gain Rail-to-Rail Input and Output Voltages Operates from a Single 3V (2.7V Min) to ±5V Supply Low Noise: 36µVRMS for fC = 25.6kHz, 60µVRMS for fC = 256kHz fC Accuracy < ±2% (Typ) DC Offset < 1mV Cascadable to Form 8th Order Lowpass Filters Available in Narrow SSOP-16 Package Typical Application
