LM101AQML Operational Amplifiers Literature Number: SNOSAI0

The LM101A is a general purpose operational amplifier which features improved performance over industry stan- dards 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  Guaranteed drift characteristics  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 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.

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is intended to be functional, but do no guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated u nder the listed test conditions. Note 3: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage. Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package junction to ambient thermal resistance), and T A (ambient temperature). The maximum allowable power dissipation at any temperature is P Dmax =( TJmax −T A)/ θJA or the number given in the Absolute Maximum Ratings, whichever is lower.

Although the LM101A is designed for trouble free operation, experience has indicated that it is wise to observe certain precautions given below to protect the devices from abnor- mal operating conditions. It might be pointed out that the advice given here is applicable to practically any IC op amp, although the exact reason why may differ with different de- vices. When driving either input from a low-impedance source, a limiting resistor should be placed in series with the input lead to limit the peak instantaneous output current of the source to something less than 100 mA. This is especially important when the inputs go outside a piece of equipment where they could accidentally be connected to high voltage sources. Large capacitors on the input (greater than 0.1 µF) should be treated as a low source impedance and isolated with a resistor. Low impedance sources do not cause a problem unless their output voltage exceeds the supply voltage. How- ever, the supplies go to zero when they are turned off, so the isolation is usually needed. The output circuitry is protected against damage from shorts to ground. However, when the amplifier output is connected to a test point, it should be isolated by a limiting resistor, as test points frequently get shorted to bad places. Further, when the amplifer drives a load external to the equipment, it is also advisable to use some sort of limiting resistance to preclude mishaps. Precautions should be taken to insure that the power sup- plies for the integrated circuit never become reversed — even under transient conditions. With reverse voltages greater than 1V, the IC will conduct excessive cur- rent, fusing internal aluminum interconnects. If there is a possibility of this happening, clamp diodes with a high peak current rating should be installed on the supply lines. Rever- sal of the voltage between V + and V− will always cause a problem, although reversals with respect to ground may also give difficulties in many circuits. The minimum values given for the frequency compensation capacitor are stable only for source resistances less than 10 kΩ, stray capacitances on the summing junction less than 5 pF and capacitive loads smaller than 100 pF. If any of these conditions are not met, it becomes necessary to over- compensate the amplifier with a larger compensation capaci- tor. Alternately, lead capacitors can be used in the feedback network to negate the effect of stray capacitance and large feedback resistors or an RC network can be added to isolate capacitive loads. Although the LM101A is relatively unaffected by supply by- passing, this cannot be ignored altogether. Generally it is necessary to bypass the supplies to ground at least once on every circuit card, and more bypass points may be required if more than five amplifiers are used. When feed-forward compensation is employed, however, it is advisable to by- pass the supply leads of each amplifier with low inductance capacitors because of the higher frequencies involved.
