Feedback Resistor Selection
The small-signal bandwidth of the LT1395/LT1396/LT1397
is set by the external feedback resistors and the internal
junction capacitors. As a result, the bandwidth is a func-
tion of the supply voltage, the value of the feedback

resistor, the closed-loop gain and the load resistor. The
LT1395/LT1396/LT1397 have been optimized for 5V
supply operation and have a – 3dB bandwidth of 400MHz
at a gain of 1 and 350MHz at a gain of 2. Please refer to the
resistor selection guide in the Typical AC Performance
table.
