LM6164/LM6264/LM6364 High Speed Operational Amplifier May 1999 LM6164/LM6264/LM6364 High Speed Operational Amplifier General Description The LM6164 family of high-speed amplifiers exhibits an excellent speed-power product in delivering 300V per µs and 175 MHz GBW (stable down to gains as low as +5) 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.

All numbers apply for packages soldered directly into a printed circuit board. Note 4: Limits are guaranteed by testing or correlation. Note 5: 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 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. Exceeding 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). 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.

Since this compensation involved adding emitter-degeneration resistors in the op amp’s input stage, the open-loop gain was reduced as the stability increased. Gain error due to reduced AVOL is most apparent at high gains; thus, the uncompensated LM6365 is appropriate for gains of 25 or more. If unity-gain operation is desired, the LM6361 should be used. The LM6361, LM6364, and LM6365 have the same high slew rate (typically 300 V/µs), regardless of their compensation. The LM6364 is unusually tolerant of capacitive loads. Most op amps tend to oscillate when their load capacitance is greater than about 200 pF (in low-gain circuits). However, load capacitance on the LM6364 effectively increases its compensation capacitance, thus slowing the op amp’s response and reducing its bandwidth. The compensation is not ideal, though, and ringing or oscillation may occur in low-gain circuits with large capacitive loads. To overcompensate the LM6364 for operation at gains less than 5, 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 5. Power supply bypassing will improve the stability and transient response of the LM6364, and is recommended for every design. 0.01 µF to 0.1 µF ceramic capacitors should be used (from each supply “rail” to ground); if the device is far away from its power supply source, 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, so that circuit gain unintentionally varies 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. www.national.com 8 Typical Applications Offset Voltage Adjustment Video-Bandwidth Amplifier DS009153-10 DS009153-12 Noise-Gain Compensation for Gains ≤5 DS009153-11 RXCX ≥ (2π • 25 MHz)−1 5 RX = R1 + RF(1 + R1/R2) 9 www.national.com Physical Dimensions inches (millimeters) unless otherwise noted Ceramic Dual-In-Line Package (J) Order Number LM6164J/883 NS Package Number J08A Molded Package SO (M) Order Number LM6364M NS Package Number M08A www.national.com 10 Physical Dimensions inches (millimeters) unless otherwise noted (Continued) Molded Dual-In-Line Package (N) Order Number LM6264N or LM6364N NS Package Number N08E 10-Pin Ceramic Flatpak Order Number LM6164W/883 NS Package Number W10A 11 www.national.com LM6164/LM6264/LM6364 High Speed Operational Amplifier Notes LIFE SUPPORT POLICY NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION.
