The LTC
1065 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
VRMS clock feedthrough of the device is considerably
lower than other existing monolithic filters.
The LTC1065 wideband noise is 80
VRMS and it can
process large AC input signals with low distortion. With
±7.5V supplies, for instance, the filter handles up to
4VRMS (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 2VRMS and 2.5VRMS.
The LTC1065 is available in 8-pin miniDIP and 16-pin SW
packages. For a Butterworth response, see LTC1063 data
sheet. The LTC1065 is pin compatible with the LTC1063.
