LT1567 - 1.4nV/Rt.Hz 180MHz Filter Building Block
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 at www.linear.com 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.
