EL2120C
100 MHz Current Feedback Amplifier
Applications Information
Contd
When the EL2120C disables it turns off very rapidly for inputs of
g
1V or less and the output sags
more slowly for inputs larger than this For inputs as large as
g
2 5V the output current can be
absorbed by another EL2120C simultaneously enabled Under these conditions switching will be prop-
erly completed in 50 ns or less
The greater thermal resistance of the SO-8 package requires that the EL2120C be operated from
g
10V
supplies or less to maintain the 150 C maximum die temperature over the commercial temperature
range The P-DIP package allows the full
g
16 5V supply operation
