DESCRIPTIO
DC Accurate, Clock-Tunable
The LTC
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 is
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 inter-
nal or external clock. The clock-to-cutoff frequency ratio is
100:1. The on-board clock is power supply independent,
and it is programmed via an external RC. The 50µV
clock feedthrough is considerably reduced over existing
monolithic filters.
The LTC1063 wideband noise is 95µV
process large AC input signals with low distortion. With
±7.5V supplies, for instance, the filter handles up to
4V
below 0.02%; 80dB dynamic ranges (S/N +THD) is ob-
tained with input levels between 1V
The LTC1063 is available in 8-pin miniDIP and 16-pin SO
wide packages. For a linear phase response, see LTC1065
data sheet.
