Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. 

Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number given in the Absolute Maximum Ratings, whichever is lower. 

Note 3: For supply voltages less than +15V, the absolute maximum input voltage is equal to the supply voltage. 

Note 4: Continuous short circuit is allowed for case temperatures to 125 C and ambient temperatures to 75 C for LM101A.  

Note 5: Human body model, 100 pF discharged through 1.5K Ohms.  

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 of LM101A 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
-  Slew rate of 10V/uS as a summing amplifier
This amplifier LM101A 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. LM101A 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 LM101A 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, LM101A can give lower offset voltage and a drift at a lower cost.
