LTC1061

High Performance Triple

Universal Filter Building Block

DESCRIPTIO

EATURE

■

The LTC1061 consists of three high performance, 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.

Up to 6th Order Filter Functions with a Single 20-Pin

0.3" Wide Package

Center Frequency Range up to 35kHz

f_O× Q Product up to 1MHz

Guaranteed Center Frequency and Q Accuracy Over

Temperature

Guaranteed Low Offset Voltages Over Temperature

90dB Signal-to-Noise Ratio

Filter Operates from Single 4.7V Supply and up to

±8V Supplies

■

Guaranteed Filter Specifications with ±5V Supply and

±2.37V Supply

■

Low Power Consumption with Single 5V Supply

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.
