Product Details
The LTC1067/LTC1067-50 consist of two identical rail-to-rail, high accuracy and very wide dynamic range 2nd order switched-capacitor building blocks. Each building block, together with three to five resistors, provides 2nd order filter functions such as bandpass, highpass, lowpass, notch and allpass. High precision 4th order filters are easily designed.
The center frequency of each 2nd order section is tuned by the external clock frequency. The internal clock-to-center frequency ratio (100:1 for the LTC1067 and 50:1 for the LTC1067-50) can be modified by the external resistors. These devices have a double sampled architecture which places aliasing and imaging components at twice the clock frequency. The LTC1067-50 is a low power device consuming about one half the current of the LTC1067. The LTC1067-50’s typical supply current is about 1mA from a 3.3V supply.
The LTC1067 and LTC1067-50 are available in 16-pin narrow SSOP and SO packages.
Mask programmable versions of the LTC1067 and LTC1067-50, with thin film resistors on-chip and custom clock-to-cutoff frequency ratios, can be designed in an SO-8 package to realize application specific monolithic filters. Please contact LTC Marketing for more details.
