The LT1568 is an ultra low noise (92 dB SNR) high frequency filter building block for channel antialiasing or reconstruction applications. The LT1568 provides a pair of matched second order filter sections integrated on a single chip. The LT1568 features differential outputs, making it suitable for single-ended to differential conversion and driving high-speed A/D converters. The device can be used as a dual matched 2nd or 3rd order lowpass filter. The LT1568 operates from a single 3 V to ± 5 V supply and has a power shutdown pin. Offered in the 16-pin narrow body SSOP package that occupies the footprint of an SO-8, the LT1568 is available for operation over the commercial and industrial temperature ranges.
