LM101A/LM201A/LM301A

Operational Amplifiers

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.

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

(LM101A/LM201A)

3 mV maximum over temperature

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.

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 sup-

ply voltage ranges

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.

•

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
