Description
AI
The LT1567 is an analog building block optimized for very low noise high frequency filter applications. It contains two wideband rail-to-rail operational amplifiers, one of them internally configured as a unity-gain inverter. With the addition of a few passive components, the LT1567 becomes a flexible second order filter section with cutoff frequency (fC) up to 5MHz, ideal for antialiasing or for channel filtering in high speed data communications systems. A spreadsheet-based design tool is available for designing lowpass and bandpass filters using the LT1567.In addition to low noise and high speed, the LT1567 features single-ended to differential conversion for direct driving of high speed differential input A/D converters. The LT1567 operates from a total power supply voltage of 2.7V to 12V and supports signal-to-noise ratios above 100dB.The LT1567 is available in an 8-lead MSOP package.ApplicationsLow Noise, High Speed Filters to 5MHzLow Noise Differential CircuitsCommunication Channel or Roofing FiltersAntialias or Reconstruction FilteringVideo Signal ProcessingSingle-Ended to Differential Conversion
