DC266B-B

DC266B-B demonstration circuit is for the evaluation of 8th order filter circuits using an LTC1562-2. The LTC1562-2 is quad 2nd order active-RC filter building block. The LTC1562-2 2nd order section can be configured with external resistors to implement lowpass and narrow or wide band bandpass filters. For other possible LTC1562-2 configurations, the DC226B-B has unused pads for 0805 surface mount resistors and capacitors preconfigured with PCB traces to allow for the following filter circuits: 1. 8th order lowpass filter, dual 4th or 5th order lowpass filter, 8th order narrow band bandpass and 8th order wide band bandpass.

• Frequency range for a lowpass filter is 20KHz to 300KHz
• Frequency range for a bandpass filter is 40KHz to 250KHz
