NCS2501
1.1 mA 200 MHz Current
Feedback Op Amp with
Enable Feature
NCS2501 is a 1.1 mA 200 MHz 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. This device features
an enable pin.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
3. Power dissipation must be considered to ensure maximum junction temperature (T
J
) is not exceeded.
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.
