The LTC1065 is the first monolithic filter providing both
clock-tunability with low DC output offset and over 12-bit
DC accuracy. The frequency response of the LTC1065
closely approximates a 5th order Bessel 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 typically 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 nearly power supply inde-
pendent and it is programmed via an external RC. The
50
μ
V
RMS
clock feedthrough of the device is considerably
lower than other existing monolithic filters.
The LTC1065 wideband noise is 80
μ
V
RMS
and it can
process large AC input signals with low distortion. With
±
7.5V supplies, for instance, the filter handles up to
4V
RMS
(94dB S/N ratio) while the standard 1kHz THD is
below 0.005%; 87dB dynamic range (S/N + THD) is ob-
tained with input levels between 2V
RMS
and 2.5V
RMS
.
The LTC1065 is available in 8-pin miniDIP and 16-pin SOL.
For a Butterworth response, see LTC1063 data sheet. The
LTC1065 is pin compatible with the LTC1063.
