THS4221 and THS4225 EVM Applications
   !" #
Example applications are presented in this chapter. These applications dem-
onstrate the most popular circuits to the user, but many other circuits can be
constructed. The user is encouraged to experiment with different circuits, ex-
ploring new and creative design techniques. That is the function of an evalua-
tion board.
Schematic diagrams and equations shown are for the THS4221 EVM,
however it should be easy for the user to adapt the circuit and discussion for
the THS4225 EVM.
