LT1568  
Very Low Noise,  
High Frequency Active RC,  
Filter Building Block  
DESCRIPTIO  
U
FEATURES  
The LT®1568 is an easy-to-use, active-RC filter building  
block with rail-to-rail inputs and outputs. The internal ca-  
pacitors of the IC and the GBW product of the internal low  
noiseopampsaretrimmedsuchthatconsistentandrepeat-  
able filter responses can be achieved. With a single resis-  
tor value, the LT1568 provides a pair of matched 2-pole  
Butterworth lowpass filters with unity gain suitable for I/Q  
channels.  
Up to 10MHz Center Frequency on a Single 3V  
Supply  
Easy to Use—A Single Resistor Value Sets Lowpass  
Cutoff Frequency (200kHz ≤ ƒC 5MHz), Unequal  
Resistor Values Extend Cutoff Frequency Up to  
10MHz  
Extremely Flexible—Different Resistor Values  
Allow Lowpass Transfer Functions with or Without  
Gain (Butterworth, Chebyshev or Custom)  
SNR = 92dB (ƒC = 2MHz, 2VP-P  
THD = –84dB (ƒC = 2MHz, 1VP-P  
Internal Capacitors Trimmed to ±0.75%  
Single 4-Pole Lowpass Filter or Matched Pair of  
2-Pole Lowpass Filters  
Can be Connected as a Bandpass Filter  
Single-Ended or Differential Output  
Operates from Single 3V (2.7V Min) to ±5V Supply  
Rail-to-Rail Input and Output Voltages  
Byusingunequal-valuedexternalresistors,thetwo2-pole  
sections can create different frequency responses or  
gains. In addition, the two stages may be cascaded to  
create a single 4-pole filter with a programmable re-  
sponse. Capable of cutoff frequencies up to 10MHz, the  
LT1568 is ideal for antialiasing or channel filtering in high  
speed data communications systems. The LT1568 can  
also be used as a bandpass filter.

)
TheLT1568featuresverylownoise, supportingsignal-to-  
noise ratios of over 90dB. It also provides single-ended to  
differential signal conversion for directly driving high  
speed A/D converters. The LT1568 has a shutdown mode  
that reduces supply current to approximately 0.5mA on a  
5V supply.
