LTC1563-2/LTC1563-3

Active RC, 4th Order

Lowpass Filter Family

DESCRIPTIO

FEATURES

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 (256Hz < f_C< 256kHz)

Extremely Flexible—Different Resistor Values

■

Allow Arbitrary Transfer Functions with or without

Gain (256Hz < f_C< 256kHz)

■

Supports Cutoff Frequencies Up to 360kHz Using

FilterCAD^TM

■

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

R = 10k (256kHz/f_C); f_C= Cutoff Frequency

■

where f_Cis 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.

Rail-to-Rail Input and Output Voltages

Operates from a Single 3V (2.7V Min) to ±5V Supply

Low Noise: 36µV_RMSfor f_C= 25.6kHz, 60µV_RMSfor

f_C= 256kHz

f_CAccuracy < ±2% (Typ)

DC Offset < 1mV

Cascadable to Form 8th Order Lowpass Filters

Available in Narrow SSOP-16 Package

■

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.

■

The LTC1563-Xs are available in the narrow SSOP-16

package (Same footprint as an SO-8 package).
