LTC1063
The LTC1063 is the first monolithic lowpass filter simultaneously offering outstanding DC and AC performance. It features internal or external clock tunability, cutoff frequencies up to 50kHz, 1mV typical output DC offset, and a dynamic range in excess of 12bits for over a decade of input voltage.
The LTC1063 approximates a 5-pole Butterworth lowpass filter. The unique internal architecture of the filter allows outstanding amplitude matching from device to device. Typical matching ranges ...
