Wideband High Speed Operational Amp

Description:

The NTE871 is a large–signal wideband, high speed operational amplifier which has a unity gain

crossover frequency (fT) of approximately 38MHz and an open–loop, 3dB corner frequency of approx-

imately 110kHz. It can operate at a total supply voltage of from 14 to 36 volts (±7 to ±18 votls when

using split supplies) and can provide at least 18VP–P and 30mAP–P at the output when operating from

±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–Lead TO5 package.

Note 1. If the supply voltage is less than ±15 volts, the maximum input voltage to GND is equal to

the supply voltage.

Note 2. The NTE871 does not contain circuitry to protect against short circuits in the output.
