DC104B-B

DC104B-B is an evaluation board to evaluate the LTC1068-200CG universal low noise 8th order filter building block (200:1, FC to 25KHz). The DC104B-B board is assembled with input, output and power supply test terminals, a 28-lead SSOP filter device (LTC1068-200CG), a dual op amp in an SO-8 for input or output buffers and decoupling capacitors for the filter and op amps. The filter and dual op amps share the power supply inputs to the board. Jumpers JPA to JPD on the board con-figure the filter’s second order circuit modes, jumper JP1 configures the filter for dual or single supply operation and jumpers JP2 (A-D) to JP3 (A-D) configure the op amp buffers as inverting or non-inverting. Surface mount pads are available on the board for 1206 size surface mount resistors.

• Clock-to-centre frequency ratio is set to 200:1
