NTE869 Integrated Circuit Dual, High Speed, Programmable Current Mode (Norton) Amp Description: The NTE869 consists of two current differencing (Norton) input amplifiers. Emphasis has been placed on obtaining high frequency performance and providing user programmable amplifier operat- ing characteristics. Each amplifier is broadbanded to provide a high gain bandwidth product, fast slew rate and stable operation for an Inverting closed loop gain of 10 or greater. Pins for additional external frequency compensation are provided. The amplifiers are designed to operate from a single supply and can accommodate input commonmode voltages greater than the supply. Applications: General Purpose Video Amplifiers High Frequency, High Q Active Filters PhotoDiode Amplifiers Wide Frequency Range Waveform Generation Circuits AC Applications Work to much Higher Frequencies Features: User programmable gain bandwidth product, slew rate, input bias current, output stage biasing current and total device power dissipation.
