LM101A/LM201A/LM301A
Operational Amplifiers
General Description
The LM101A series are general purpose operational amplifi-
ers which feature improved performance over industry stan-
dards like the LM709. Advanced processing techniques
make possible an order of magnitude reduction in input cur-
rents, and a redesign of the biasing circuitry reduces the
temperature drift of input current. Improved specifications in-
clude:
• Offset voltage 3 mV maximum over temperature
• Input current 100 nA maximum over temperature
• Offset current 20 nA maximum over temperature
• Guaranteed drift characteristics
• Offsets guaranteed over entire common mode and sup-
• Slew rate of 10V/µs as a summing amplifier
Fast AC/DC Converter
Note 1: Feedforward compensation can be used to make a fast full wave rectifier without a filter.
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 compensa-
tion with a single 30 pF capacitor. It has advantages over
internally compensated amplifiers in that the frequency
compensation can be tailored to the particular applica-
tion. For example, in low frequency circuits it can be over-
compensated for increased stability margin. Or the com-
pensation 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 inte-
grators or timers, sample and hold circuits and low fre-
quency waveform generators. Further, replacing circuits
where matched transistor pairs buffer the inputs of con-
ventional 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.
