DEMO MANUAL DC338B LTC1563-2 and LTC1563-3 Fourth Order Active RC Filter ICs
●Demonstration circuit DC338B-A is for the evaluation of filter circuits using an LTC®1563-2 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 filter, and the LTC1563-3 uses six equal value resistors to implement a 4th order Bessel lowpass filter. The lowpass cutoff frequency (fC) range of an LTC1563-X filter is 256Hz to 256kHz.
●For testing and evaluation, the DC338B-A is configured as a single 4th order, 25.6kHz Butterworth lowpass filter; and the DC338B-B is configured as a single 4th order, 25.6kHz Bessel lowpass filter.
●For other LTC1563-X configurations, the DC338B has un-used pads for 0805 surface mount resistors and capacitors preconfigured with PCB traces to allow for the following LTC1563-X filter circuits:
■4th order lowpass filter
■5th order lowpass filter
■4th order narrow bandpass filter
■4th order wide bandpass filter
●Refer to the LT1563-X data sheet for additional information about filter circuit configurations.
