## DC338B-B - LTC1563-3CGN Demo Board | Universal Lowpass Filter

Jul 12th 2016

Demonstration circuit DC338B-A is for the evaluation of filter circuits using an LTC1563-2 and DC338B-B for an LTC1563-3. LTC1563-2 and LTC1563-3 are dual 2nd order active RC filter building blocks with precision ±1.5% capacitors. The LTC1563-2 uses six equal value resistors to implement a 4th order Butterworth lowpass ...

## Sub-Microamp RMS Current Measurement for Improved 32kHz Quartz Crystal Performance - LT1028, LT1222, LTC1563-2, LTC1968, LT1077

Jun 15th 2008

Quartz crystal RMS operating current is critical to long-term stability, temperature coefficient and reliability. Accurate determination of RMS crystal current, especially in micropower types, is complicated by the necessity to minimize introduced parasitics, particulary capacitance, which corrupt crystal operation. This video ...

## Clock Tuned, Highly Selective Notch Filter

Jan 1st 1998

This circuit shows a quick, clean way to tune a notch filter’s center frequency by varying a single resistor, which could be switched. The LTC1062 switched capacitor filter and A1 form a clock tunable notch (see LTC1062 data sheet). O1, running from the 5V supply, furnishes the clock, which is level shifted by Q1 to drive ...
