NTE915
Integrated Circuit
High−Speed Operational Amplifier
Description;
The NTE915 is a High−Speed, High−Gain, Monolithic Operational Amplifier. It is intended for use in
a wide range of applications where fast signal acquistion or wide bandwidth is required. The NTE915
acquistion or wide bandwidth is required. The NTE915 features fast settling time, high slew rate, low
offsets and high output swing for large signal applications. In addition, the device displays excellent
temperature stability and will operate over a wide range of supply voltages. The NTE915 is ideally
suited for use in A/D and D/A converters, active filters, deflection amplifiers, video amplifiers, phase−
locked loops, multiplexed analog gates, precision comparators, sample and holds and general feedback applications requiring DC wide bandwidth operation.
