LTC1068 Series
APPLICATIONS INFORMATION
A Surface Mount Printed Circuit Layout
A very compact surface mount printed circuit layout can
be designed with 0603 size surface mount resistors,
capacitors and a 28-pin SSOP of the LTC1068 product
family. An example of a printed circuit layout is shown in
the folowing figures for an 8th order elliptic bandpass
filter. The total board area of this 8th order filter is 1" by
0.8". No attempt was made to design the smallest possible
printed circuit layout.
