LTC1560-1
APPLICATIONS INFORMATION
The performance of the LTC1560-1 can be easily evaluated
by using demo board 135A which can be obtained through
LTC marketing. Figure 2 shows the circuit connection of
the LTC1560-1 in demo board 135A. The filter cutoff
frequency can be switched via S2 and the power savings
mode can also be activated via S1. The output of the filter
is buffered by U2, an LT®1360 op amp. The buffering can
be bypassed by using jumper JP1. Figure 3 shows the
demo board layout.
