TC1059 1059fd Sinewave Oscillators Sweepable Bandpass/Notch Filters Full Audio Frequency Filters Tracking Filters 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 T L or CMOS Compatible Separate Highpass (or Notch or Allpass), Bandpass, Lowpass Outputs High Performance Switched Capacitor Universal Filter 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. The filter can handle input frequencies up to 100kHz. The uncommitted op amp can be used to obtain additional allpass and notch functions, for gain adjustment or for cascading techniques. 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. The LTC1059 can be operated with single or dual supplies ranging from 2.37V to 8V (or 4.74V to 16V single supply). The LTC1059 is manufactured by using Linear Technology’s enhanced LTCMOS TM silicon gate process.

Linear Technology Corporation makes no represen- tation that the interconnection of its circuits as described herein will not infringe on existing patent rights. The LTC1059 is compatible with the LTC1060. All the LTC1059 pins are functionally equivalent to the LTC1060 pins bearing the same title. For a detailed pin description and definition of various modes of operation refer to the LTC1060 data sheet. The LTC1059 is typically “faster” than the LTC1060 especially under single 5V (or 2.5V) supply operation. This becomes apparent through the Typical Performance Characteristics of the part. All the graphs shown in this data sheet have been drawn under the same test conditions as in the LTC1060 data sheet; they are also numbered in the same order.
