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–mode voltages greater than the supply.
Applications:
D General Purpose Video Amplifiers
D High Frequency, High Q Active Filters
D Photo–Diode Amplifiers
D Wide Frequency Range Waveform Generation Circuits
D AC Applications Work to much Higher Frequencies
Features:
D User programmable gain bandwidth product, slew rate, input bias current, output stage biasing
current and total device power dissipation.
D High gain bandwidth product (I_SET = 0.5mA)
400MH_Z for A_V = 10 to 100
30MH_Z for A_V = 1
D Current differencing inputs allow high common–mode input voltages
D Operates from a single 5V to 22V supply
D Large inverting amplifier output swing, 2mV to V_CC –2V
D Low spot noise, 6nV/√Hz, for f > 1kH_Z
