LM6164/LM6264/LM6364
High Speed Operational Amplifier
LM6164/LM6264/LM6364 High Speed Operational Amplifier
May 1999
General Description
The LM6164 family of high-speed amplifiers exhibits an excellent speed-power product in delivering 300V per µs and
175 MHzGBW (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
tegrated 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 forcomplex and expensive dielectric isolation.

Applications Tips
The LM6364 hasbeen compensated forgains of 5or greater
(over specified rangesof temperature, powersupply voltage,
and load). 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 A
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 isnot
ideal, though, and ringing or oscillation may occur in
low-gain circuits with large capacitiveloads. Toovercompensate 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.
is most apparent at high
VOL
DS009153-3
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 andlead 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, asopposed to being soldered into the
circuit, the additional input capacitance may degrade circuit
performance.
