NCS2511
1 GHz Current Feedback
Op Amp
NCS2511 is a 1 GHz current feedback monolithic operational
amplifier featuring high slew rate and low differential gain and phase
error. The current feedback architecture allows for a superior
bandwidth and low power consumption.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
3. Power dissipation must be considered to ensure maximum junction temperature (T
J
) is not exceeded.
MAXIMUM POWER DISSIPATION (mW)
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated is
limited by the associated rise in junction temperature. For
the plastic packages, the maximum safe junction
temperature is 150°C. If the maximum is exceeded
momentarily, proper circuit operation will be restored as
soon as the die temperature is reduced. Leaving the device
in the “overheated’’ condition for an extended period can
result in device damage. To ensure proper operation, it is
important to observe the derating curves.
