TYPICAL APPLICATIO
U
The LTC
®
1061 consists of three high performance, univer-
sal filter building blocks. Each filter building block together
with an external clock and 2 to 5 resistors can produce
various second order functions which are available at its
three output pins. Two out of three always provide low-
pass and bandpass functions while the third output pin
can produce highpass or notch or allpass. The center
frequency of these functions can be tuned with an external
clock or an external clock and a resistor ratio. For Q < 5, the
center frequency ranges from 0.1Hz to 35kHz. For Qs of 10
or above, the center frequency ranges from 0.1Hz to
28kHz.
The LTC1061 can be used with single or dual supplies
ranging from ±2.37V to ±8V (or 4.74V to 16V). When the
filter operates with supplies of ±5V and above, it can
handle input frequencies up to 100kHz.
The LTC1061 is compatible with the LTC1059 single
universal filter and the LTC1060 dual. Higher than 6th
order functions can be obtained by cascading the LTC1061
with the LTC1059 or LTC1060. Any classical filter realiza-
tion can be obtained.
