The LTC1063 is the first monolithic filter providing both clock-tunability, low DC output offset and over 12-bit DC
accuracy. The frequency response of the LTC1063 closely approximates a 5th order Butterworth polynomial. With appropriate PCB layout techniques the output DC offset typically 1mV and is constant over a wide range of clock frequencies. With ±5V supplies and ±4V input voltage range, the CMR of the device is 80dB.

The filter cutoff frequency is controlled either by an internal or external clock. The clock-to-cutoff frequency ratio 100:1. The on-board clock is power supply independent, and it is programmed via an external RC. The 50mVRMS clock feedthrough is considerably reduced over existing monolithic filters.

The LTC1063 wideband noise is 95mVRMS, and it can process large AC input signals with low distortion. With
±7.5V supplies, for instance, the filter handles up 4VRMS (92dB S/N ratio) while the standard 1kHz THD below 0.02%; 80dB dynamic ranges (S/N +THD) is obtained with input levels between 1VRMS and 2.3VRMS.

The LTC1063 is available in 8-pin miniDIP and 16-pin SOL. For a linear phase response, see LTC1065 data sheet.
