DESCRIPTIO
The LT
very low noise high frequency filter applications. It con-
tains 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 (f
ing or for channel filtering in high speed data communi-
cations 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.
