LM6165/LM6265/LM6365
High Speed Operational Amplifier
General Description
The LM6165 family of high-speed amplifiers exhibits an excellent speed-power product in delivering 300 V/µs and
725 MHz GBW (stable for gains as low as +25) with only
5 mA of supply current. Further power savings and application convenience are possible by taking advantage of the
wide dynamic range in operating supply voltage which extends all the way down to +5V.
These amplifiers are built with National’s VIP
™
(VerticallyIntegrated PNP) process which produces fast PNP transistors
that are true complements to the already fast NPN devices.
This advanced junction-isolated process delivers high speed
performance without the need for complex and expensive dielectric isolation.

Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: Continuous short-circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150˚C.
Note 3: The typical junction-to-ambient thermal resistance of the molded plastic DIP (N) is 105˚C/Watt, and the molded plastic SO (M) package is 155˚C/Watt, and
the cerdip (J) package is 125˚C/Watt. All numbers apply for packages soldered directly into a printed circuit board.
Note 4: All limits guaranteed by testing or correlation.
Note 5: For single supply operation, the following conditions apply: V+=5V, V−=0V, V
CM
=
2.5C, V
OUT
=
2.5V. Pin1&Pin8(V
OS
Adjust) are each connected
to Pin 4 (V−) to realize maximum output swing. This connection will degrade V
OS
.
Note 6: C
L
≤ 5pF.
Note 7: In order to achieve optimum AC performance, the input stage was designed without protective clamps. Exeeding the maximum differential input voltage results in reverse breakdown of the base-emitter junction of one of the input transistors and probable degradation of the input parameters (especially V
OS,IOS
, and
Noise).

Note 8: 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 test circuit
used consists of the human body model of 100 pF in series with 1500Ω.
Note 9: V

0.8V step. For supply
=

5V, V
IN
=
0.2V step.
Note 10: Voltage Gain is the total output swing (20V) divided by the input signal required to produce that swing.
Note 11: The voltage between V
+
and either input pin must not exceed 36V.
Note 12: A military RETS electrical test specification is available on request. At the time of printing, the LM6165J/883 RETS spec complied with the Boldface limits
in this column. The LM6165J/883 may also be procured as Standard Military Drawing

Simplified Schematic
Application Tips
The LM6365 is stable for gains of 25 or greater. The LM6361
and LM6364, specified in separate datasheets, are compensated versions of the LM6365. The LM6361 is unity-gain
stable, while the LM6364 is stable for gains as low as 5. The
LM6361, and LM6364 have the same high slew rate as the
LM6365, typically 300 V/µs.
To use the LM6365 for gains less than 25, a series
resistor-capacitor network should be added between the input pins (as shown in the Typical Applications, Noise Gain
Compensation) so that the high-frequency noise gain rises
to at least 25.
Power supply bypassing will improve stability and transient
response of the LM6365, and is recommended for every design. 0.01 µF to 0.1 µF ceramic capacitors should be used
(from each supply “rail” to ground); an additional 2.2 µF to
10 µF (tantalum) may be required for extra noise reduction.
Keep all leads short to reduce stray capacitance and lead inductance, and make sure ground paths are low-impedance,
especially where heavier currents will be flowing. Stray capacitance in the circuit layout can cause signal coupling between adjacent nodes, and can cause circuit 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.
