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 common鈥搈ode voltages greater than the supply.
