LM6365

LM6165/LM6265/LM6365 High Speed Operational Amplifier May 1999 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™ (Vertically Integrated 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. n n n n n n n High GBW product: 725 MHz Low supply current: 5 mA Fast settling: 80 ns to 0.1% Low differential gain: < 0.1% Low differential phase: < 0.1˚ Wide supply range: 4.75V to 32V Stable with unlimited capacitive load Applications n n n n Video amplifier Wide-bandwidth signal conditioning Radar Sonar Features n High slew rate: 300 V/µs Connection Diagrams 10-Lead Flatpak Top View DS009152-14 Order Number LM6165W/883 See NS Package Number W10A DS009152-8 Order Number LM6165J/883 See NS Package Number J08A Order Number LM6365M See NS Package Number M08A Order Number LM6265N or LM6365N See NS Package Number N08E VIP™ is a trademark of National Semiconductor Corporation. © 1999 National Semiconductor Corporation DS009152 www.national.com Connection Diagrams Military −55˚C ≤ TA ≤ +125˚C (Continued) Package Commercial 0˚C ≤ TA ≤ +70˚C LM6365N 8-Pin Molded DIP 8-Pin Ceramic DIP LM6365M 8-Pin Molded Surface Mt. 10-Lead Ceramic SOIC 10-Pin Ceramic Flatpak W10A M08A WG10A N08E J08A NSC Drawing Temperature Range Industrial −25˚C ≤ TA ≤ +85˚C LM6265N LM6165J/883 5962-8962501PA LM6165WG/883 5962-8962501XA LM6165W883 5962-8962501HA www.national.com 2 Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.

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, VCM = 2.5C, VOUT = 2.5V. Pin 1 & Pin 8 (VOS Adjust) are each connected to Pin 4 (V−) to realize maximum output swing. This connection will degrade VOS. Note 6: CL ≤ 5 pF. 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 VOS, IOS, and Noise). www.national.com 4 AC Electrical Characteristics Note 9: VIN = 0.8V step. For supply = ± 5V, VIN = 0.2V step. (Continued) 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 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 #5962-8962501PA.

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.
