NTE871
Integrated Circuit
Wideband High Speed Operational Amp
Description:
The NTE871 is a large鈥搒ignal wideband, high speed operational amplifier which has a unity gain
crossover frequency (f
T
) of approximately 38MHz and an open鈥搇oop, 3dB corner frequency of approx-
imately 110kHz. It can operate at a total supply voltage of from 14 to 36 volts (鹵7 to
鹵18
votls when
using split supplies) and can provide at least 18V
P鈥揚(yáng)
and 30mA
P鈥揚(yáng)
at the output when operating from
鹵15
volt supplies. The NTE871 can be compensated with a single external capacitor and has DC
offset adjust terminals for those applications requiring offset null.
The NTE871 circuit contains both bipolar and PMOS transistors on a single monlithic chip and is sup-
plied in a 8鈥揕ead TO5 package.
