NCS2540
Triple 750 MHz Voltage
Feedback Op Amp with
Enable Feature
NCS2540 is a triple 750 MHz voltage feedback monolithic
operational amplifier featuring high slew rate and low differential gain
and phase error. The voltage feedback architecture allows for a
superior bandwidth and low power consumption. This device features
an enable pin.
