EL2120C
100 MHz Current Feedback Amplifier
Applications Information Ð Contd.
When the EL2120C disables, it turns off very rapidly for inputs of 1V or less, and the output sags

more slowly for inputs larger than this. For inputs as large as 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 10V
supplies or less to maintain the 150 C maximum die temperature over the commercial temperature
