1_mV_OFFSET，CLOCK_TUNABLE，MONOLITHIC_5_POLE_LOW_PASS_FILTER

The LTC1063 is the first monolithic low-pass fil-ter that simultaneously offers outstanding dc and ac performance. It features internal or external clock tunability, cutoff frequencies up to 50 kHz, 1-mV typ-ical output dc offset, and a dynamic range in excess of 12 bits for over a decade of input voltage.The LTC1063 approximates a 5-pole Butterworth low-pass filter. The unique internal architecture of the filter allows outstanding amplitude matching from device to device. Typical matching ranges from 0.01 dB at 25% of the filter passband to 0.05 dB at 50% of the filter passband.An internal or external clock programs the filter's cutoff frequency. The clock-to-cutoff frequency ratio is 100:1. In the absence of an external clock, the LTC1063's internal precision oscillator can be used. An external resistor and capacitor set the device's internal clock frequency.
