LM101A/LM201A/LM301A Operational Amplifiers
August 2000
LM101A/LM201A/LM301A
Operational Amplifiers
General Description
The LM101A series are general purpose operational ampli-
fiers which feature improved performance over industry stan-
dards 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. Improved specifications
include:
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
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
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, replac-
ing 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.
Offsets guaranteed over entire common mode and sup-
ply 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
Fast AC/DC Converter

Note 1:
Feedforward compensation can be used to make a fast full wave rectifier without a filter.

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 and AC 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.
