DC104B-C

DC104B-C is a surface mount printed circuit board for the evaluation of Li-near Technology’s LTC1068 in a 28-lead SSOP package. The LTC1068 product family consists of four monolithic clock-tunable filter building blocks. The board is assembled with input, output and power supply test terminals, a 28-lead SSOP filter device (LTC1068CG series), 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.
