High Performance Triple

Universal Filter Building Block

DESCRIPTIO

FEATURES

TheLTC^®1061consistsofthreehighperformance,univer-

salfilterbuildingblocks.Eachfilterbuildingblocktogether

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

clockoranexternalclockandaresistorratio. ForQ<5, the

centerfrequencyrangesfrom0.1Hzto35kHz.ForQsof 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.

■

Available in 20-Pin DIP and 20-Pin SO Wide Package

APPLICATIO S

The LTC1061 is compatible with the LTC1059 single

universal filter and the LTC1060 dual. Higher than 6th

orderfunctionscanbeobtainedbycascadingtheLTC1061

with the LTC1059 or LTC1060. Any classical filter realiza-

tion can be obtained.
