Product Overview

The LT1568CGN#PBF is an easy-to-use, high frequency active-RC Filter Building Block with rail-to-rail inputs and outputs. The internal capacitors of the IC and the GBW product of the internal low noise op amps are trimmed such that consistent and repeatable filter responses can be achieved. With a single resistor value, the LT1568 provides a pair of matched 2-pole Butterworth low pass filters with unity gain suitable for I/Q channels. By using unequal-valued external resistors, the two 2-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 response. 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.
  • Very low noise
  • Easy to use
  • Extremely flexible - Different resistor values allow low pass transfer functions with/without gain
  • Internal capacitors trimmed to ±0.75%
  • Single 4-pole low pass filter or matched pair of 2-pole low pass filters
  • Can be connected as a bandpass filter
  • Rail-to-rail input and output voltages
