DESCRIPTION
The LT®1567 is an analog building block optimized for very low-noise high-frequency filter applications. It contains 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 (fC) up to 5MHz, ideal for antialiasing or for channel filtering in highspeed data communications systems.
