The LT
廬
1567 is an analog building block optimized for
very low-noise high-frequency filter applications. It con-
tains two wideband operational amplifiers, one of them
internally configured as a unity-gain inverter. With the
addition of two capacitors, the LT1567 becomes a flexible
second-order filter section with cutoff frequency (f
C
) up to
5MHz, ideal for antialiasing or for channel filtering in high-
speed data communications systems.
In addition to low noise and high speed LT1567 features
single-ended to differential conversion for direct driving of
high speed A/D converters. The LT1567 operates from a
total power-supply voltage of 2.7V to 12V and can support
signal-to-noise ratios above 100dB.
The LT1567 is available in an 8-lead MSOP package.
