GAIN BANDWIDTH PRODUCT
The LMH6609 is a voltage feedback amplifier, whose closed-loop bandwidth is approximately equal to the gain-
bandwidth product (GBP) divided by the gain (A
V
). For gains greater than 5, A
V
sets the closed-loop bandwidth of
the LMH6609.
(2)
For Gains less than 5, refer to the frequency response plots to determine maximum bandwidth. For large signal
bandwidth the slew rate is a more accurate predictor of bandwidth.

OUTPUT DRIVE AND SETTLING TIME PERFORMANCE
The LMH6609 has large output current capability. The 100mA of output current makes the LMH6609 an excellent
choice for applications such as:
• Video Line Drivers
• Distribution Amplifiers
