OPERATION AMPLIFIER
General Description
The LM101A is a general purpose operational amplifier which features improved performance
over industry standards such as 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. Improved specifications include:
-
-
-
-
Offset voltage 3 mV maximum over temperature
Input current 100 nA maximum over temperture
Offset current 20 nA maximum over temperature
Offsets guaranteed over entire common mode and supply voltage ranges
Original Creation Date: 06/21/95

- Slew rate of 10V/uS as a summing amplifier
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.
