LTC1059

High Performance

Switched Capacitor Universal Filter

FEATURES

DESCRIPTIO

The LTC^®1059 consists of a general purpose, high perfor-

mance, active filter building block and an uncommitted op

amp. The filter building block together with an external

clock and 2 to 5 resistors can produce various 2nd order

functions which are available at its three output pins. Two

out of three always provide lowpass and bandpass func-

tions while the third output pin can produce notch or

highpass or allpass. The center frequency of these func-

tions can be tuned from 0.1Hz to 40kHz and is dependent

on an external clock or an external clock and a resistor

ratio. Thefiltercanhandleinputfrequenciesupto100kHz.

The uncommitted op amp can be used to obtain additional

allpass and notch functions, for gain adjustment or for

cascading techniques.

■

All Filter Parameters Guaranteed Over Temperature

Wide Center Frequency Range (0.1Hz to 40kHz)

Low Noise, Wide Dynamic Range

Guaranteed Operation for ±2.37V and ±5V Supply

Low Power Consumption

Guaranteed Clock-to-Center Frequency Accuracy of

0.8%

Guaranteed Low Offset Voltages Over Temperature

Very Low Center Frequency and Q Tempco

Clock Input T²L or CMOS Compatible

■

APPLICATIO S

Higher than 2nd order filter functions can be obtained by

cascading the LTC1059 with the LTC1060 dual universal

filter or the LTC1061 triple universal filter. Any classical

filter realization (such as Butterworth, Cauer, Bessel and

Chebyshev) can be formed.
