DESCRIPTION

· The LT1568 is an active-RC filter building block with rail-to-rail inputs and outputs, designed for high-speed data communication systems.

· It features internal capacitors and low noise op amps trimmed for consistent filter responses.

· Capable of cutoff frequencies up to 10MHz, it supports single-ended to differential signal conversion.

· Available in a 16-lead SSOP package, it includes a shutdown mode reducing supply current to 0.5mA on a 5V supply.

FEATURES

· Operates on a single 3V to 5V supply with rail-to-rail input and output voltages.

· Supports center frequencies up to 10MHz and provides a signal-to-noise ratio of over 90dB.

· Internal capacitors are trimmed to -0.75% for precision.

· Can be configured as a single 4-pole lowpass filter or a matched pair of 2-pole lowpass filters.

· Features low noise and high frequency capabilities, suitable for replacing discrete RC active filters and LC filter modules.

APPLICATIONS

· Ideal for antialiasing or channel filtering in high-speed data communications.

· Suitable for video signal processing and dual or I-and-Q channels.

· Effective in single-ended to differential conversion for driving high-speed A/D converters.

· Used in reconstruction filters and as a bandpass filter in various electronic systems.
