FEATURES

DESCRIPTION

The LM101A series are general purpose operational

• Improved Specifications include:

amplifiers which feature improved performance over

• Offset Voltage 3 mV Maximum Over

industry standards like the LM709. Advanced

Temperature (LM101A/LM201A)

processing techniques make possible an order of

• Input Current 100 nA Maximum Over

magnitude reduction in input currents, and a redesign

of the biasing circuitry reduces the temperature drift

Temperature (LM101A/LM201A)

of input current.

• Offset Current 20 nA Maximum Over

Temperature (LM101A/LM201A)

This amplifier offers many features which make its

application nearly foolproof: Overload protection on

• Specified Drift Characteristics

the input and output, no latch-up when the common

• Offsets Specified Over Entire Common Mode

mode range is exceeded, and freedom from

and Supply Voltage Ranges

oscillations and compensation with a single 30 pF

• Slew Rate of 10V/μs as a Summing Amplifier

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 ensured 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.

Fast AC-DC Converter

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