DESCRIPTION
The LM101A is a general purpose operational amplifier which features improved performance over industry
standards such as 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
• Input current 100 nA maximum over temperature
• Offset current 20 nA maximum over temperature
• Specified drift characteristics
• Offsets ensured 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 application 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.
