These amplifiers are built with National’s VIPTM (Vertically
Integrated PNP) process which provides fast transistors that
are true complements to the already fast NPN devices. This
advanced junction-isolated process delivers high speed per-
formance without the need for complex and expensive di-
electric isolation.

Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the
device beyond its rated operating conditions.
Note 2: The ESD protection circuitry between the inputs will begin to conduct when the differential input voltage reaches 8V.
Note 3: a) In addition, the voltage between the Va pin and either input pin must not exceed 36V.
b) When the voltage applied to an input pin is driven more than 0.3V below the negative supply pin voltage, a substrate diode begins to conduct. Current
through this pin must then be kept less than 20 mA to limit damage from self-heating.
Note 4: Although the output current is internally limited, continuous short-circuit operation at elevated ambient temperature can result in exceeding the maximum
allowed junction temperature of 150 C.
§
Note 5: This value is the average voltage that the weakest pin combinations can withstand and still conform to the datasheet limits. The test circuit used consists of
the human body model, 100 pF in series with 1500X.

Application Tips
The LM6362 has been decompensated for a wider gain-
Power supply bypassing is not as critical for LM6362 as it is
for other op amps in its speed class. However, bypassing
will improve the stability and transient response of the
LM6362, and is recommended for every design. 0.01 mF to
0.1 mF ceramic capacitors should be used (from each sup-
ply ‘‘rail’’ to ground); if the device is far away from its power
supply source, an additional 2.2 mF to 10 mF of tantalum
may be required for extra noise reduction.
bandwidth product than the LM6361. However, the LM6362
b
still offers stability at gains of 2 (and 1) or greater over the
specified ranges of temperature, power supply voltage, and
load. Since this decompensation involved reducing the emit-
ter-degeneration resistors in the op amp’s input stage, the
DC precision has been increased in the form of lower offset
voltage and higher open-loop gain.
Other op amps in this family include the LM6361, LM6364,
and LM6365. If unity-gain stability is required, the LM6361
should be used. The LM6364 has been decompensated for
operation at gains of 5 or more, with corresponding greater
gain-bandwidth product (125 MHz, typical) and DC preci-
sion. The fully-uncompensated LM6365 offers gain-band-
width product of 725 MHz, typical, and is stable for gains of
25 or more. All parts in this family, regardless of compensa-
tion, have the same high slew rate of 300 V/ms (typ).
Keep all leads short to reduce stray capacitance and lead
inductance, and make sure ground paths are low-imped-
ance, especially where heavier currents will be flowing.
Stray capacitance in the circuit layout can cause signal cou-
pling from one pin, input or lead to another, 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
The LM6362 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 LM6362 effectively increases its
compensation capacitance, thus slowing the op amp’s re-
sponse and reducing its bandwidth. The compensation is
not ideal, though, and ringing may occur in low-gain circuits
with large capacitive loads.

compensate for the phase lag caused by capacitance at the
inverting input. Typically, values from 2 pF to 5 pF work well;
however, best results can be obtained by observing the am-
plifier pulse response and optimizing C for the particular
f
layout.
