The LM101A series are general purpose operational amplifiers which feature improved
performance over industry standards like the LM709. Advanced processing techniques make possible an
order of magnitude reduction in input currents, and a redesign of the biasing circuitry reduces the
temperature drift of input current.
This amplifier offers many features which make its application nearly foolproof: Overload
protection on the input and output, no latch-up when the common mode range is exceeded, and freedom
from oscillations and compensation with a single 30 pF Capacitor. It has advantages over internally
compensated amplifiers in that the frequency compensation can be tailored to the particular
application. For example, in low frequency circuits it can be overcompensated for increased
stability margin or the compensation can be optimized to give more than a factor of ten improvement
in high frequency performance for most applications.
In Addition, the device provides better accuracy and lower noise in high impedance
circuitry. The low input currents also make it particularly well suited for long interval
integrators or timers, sample and hold circuits and low frequency waveform generators. Further,
replacing circuits where matched transistor pairs buffer the inputs of conventional IC op amps, It
can give lower offset voltage and a drift at a lower cost.
The LM101A is ensured over a temperature range of −55°C to +125°C, the LM201A from −25°C
to +85°C, and the LM301A from 0°C to +70°C.
