Description

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

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

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