LM101A/LM201A/LM301A
Operational Amplifiers
General Description
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.Improvedspecificationsinclude:
•
Offset voltage 3 mV maximum over temperature
(LM101A/LM201A)
•
Input current 100 nA maximum over temperature
(LM101A/LM201A)
•
Offset current 20 nA maximum over temperature
(LM101A/LM201A)
•
Guaranteed drift characteristics
•
Offsets guaranteed over entire common mode and supply voltage ranges
•
Slew rate of 10V/µs as a summing amplifier
This amplifier offers many features which make its appli-
cation 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 guaranteed 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.

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.Operating ratings indicate for which the device is functional, but
do no guarantee specific performance limits. Electrical Characteristics state DC andAC electrical specifications under particular test conditions which guarantee specific limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is given, however,the typical
value is a good indication of device performance.
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/LM201A, and 70˚C and 55˚C respectively
for LM301A.
