Note 2:The typical junction-to-ambient thermal resistance of the molded plastic DIP (N) is 105˚C/W, the molded plastic SO (M) package is 155˚C/W, and the cerdip (J) package is 125˚C/W. All numbers apply for packages soldered directly into a printed circuit board. Note 3:Limits are guaranteed by testing or correlation. Note 4:For single supply operation, the following conditions apply: V+ = 5V, V− = 0V, VCM = 2.5V, VOUT = 2.5V. Pin 1 & Pin 8 (Vos Adjust) are each connected to P i n4( V−) to realize maximum output swing. This connection will degrade VOS ,V OS Drift, and Input Voltage Noise. Note 5:C L ≤ 5p F . Note 6:In order to achieve optimum AC performance, the input stage was designed without protective clamps. Exceeding the maximum differential input voltage re- sults in reverse breakdown of the base-emitter junction of one of the input transistors and probable degradation of the input parameters (especiallyVos, Ios, and Noise). www.national.com3

Note 7:The average voltage that the weakest pin combinations (those involving Pin 2 or Pin 3) can withstand and still conform to the datasheet limits. The testcircuit used consists of the human body model of 100 pF in series with 1500Ω . Note 8:VIN = 8V step. For supply= ±5V, VIN = 5V step. Note 9:Voltage Gain is the total output swing (20V) divided by the input signal required to produce that swing. Note 10:The voltage between V+ and either input pin must not exceed 36V. Note 11:A military RETS electrical test specification is available on request. At the time of printing, the RETS6161X specs complied with allBoldfacelimits in this column. Note 12: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 not guarantee specific performance limits. For guaranteed specifications and test conditions, see the ElectricalCharacteristics. The guaranteed specifications apply only for the test conditions listed.

The LM6361 has been compensated for unity-gain opera- tion. Since this compensation involved adding emitter- degeneration resistors to the op amp’s input stage, the open-loop gain was reduced as the stability increased. Gain error due to reduced A VOL is most apparent at high gains; thus, for gains between 5 and 25, the less-compensated LM6364 should be used, and the uncompensated LM6365 is appropriate for gains of 25 or more. The LM6361, LM6364, and LM6365 have the same high slew rate, regardless of their compensation. The LM6361 is unusually tolerant of capacitive loads. Most op amps tend to oscillate when their load capacitance is greater than about 200 pF (especially in low-gain circuits). The LM6361’s compensation is effectively increased with load capacitance, reducing its bandwidth and increasing its stability. Power supply bypassing is not as critical for the LM6361 as it is for other op amps in its speed class. Bypassing will, how- ever, improve the stability and transient response and is rec- ommended for every design. 0.01 µF to 0.1 µF ceramic ca- pacitors should be used (from each supply “rail” to ground); if the device is far away from its power supply source, an ad- ditional 2.2 µF to 10 µF of tantalum may provide extra noise reduction. Keep all leads short to reduce stray capacitance and lead in- ductance, and make sure ground paths are low-impedance, especially where heavier currents will be flowing. Stray ca- pacitance in the circuit layout can cause signal coupling across adjacent nodes and can cause gain to unintentionally vary with frequency. Breadboarded circuits will work best if they are built using generic PC boards with a good ground plane. If the op amps are used with sockets, as opposed to being soldered into the circuit, the additional input capacitance may degrade circuit performance.
