APPLICATIONS INFORMATION
DC1251A Demonstration Board
The DC1251A demonstration circuit contains an LTC6601-2
(DC1251A-B). On a DC1251A the LTC6601 programming
pins can be connected through 0603 resistor jumpers. In
addition, optional surface mount capacitors and inductors
at the LTC6601 input and/or output can be installed for
additional fi ltering (a lowpass fi lter up to a 5th order can
be implemented with a DC1251A demonstration circuit).
The DC1251A has SMA connectors for the differential
input and output of the LTC6601. An on board 106MHz
lowpass RC fi lters the LTC6601 output.
