FEATURES  
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:  
Extremely Easy to Use—A Single Resistor Value  
Sets the Cutoff Frequency (2.56kHz < fC < 256kHz)  
Extremely Flexible—Different Resistor Values  
Allow Arbitrary Transfer Functions with or without  
Gain (2.56kHz < fC < 256kHz)  
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  
R = 10k (256kHz/fC); fC = Cutoff Frequency  
where fC is the desired cutoff frequency. For many appli-  
cations, this formula is all that is needed to design a filter.  
By simply utilizing different valued resistors, gain and  
other responses are achieved.  
fC Accuracy < ±2% (Typ)  
DC Offset < 1mV  
Cascadable to Form 8th Order Lowpass Filters  
Low Power Mode, fC < 25.6kHz, ISUPPLY =1mA (Typ)  
The LTC1563-X features a low power mode, for the lower  
frequency applications, where the supply current is re-  
duced by an order of magnitude and a near zero power  
shutdown mode.  
High Speed Mode, f < 256kHz, I  
= 10mA (Typ)

SUPPLY  
= 1µA (Typ)  
The LTC1563-Xs are available in the narrow SSOP-16  
package (SO-8 footprint).
