LM6162
High Speed Operational Amplifier
General Description
The LM6162 family of high-speed amplifiers exhibits an ex-
cellent speed-power product, delivering 300 V/s and
100 MHz gain-bandwidth product (stable for gains as low as
+2 or -1) 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
TM
(Vertically In-
tegrated 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 de-
vice 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 V
+
pin and either input pin must not exceed 36V.
b) When the voltage applied to an input pin is driven more than 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 al-
lowed junction temperature of 150C.
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 1500
.
Note 6: The typical thermal resistance, junction-to-ambient, of the molded plastic DIP (N package) is 105C/W. For the molded plastic SO (M package), use
155C/W. All numbers apply for packages soldered directly into a printed circuit board.
Note 7: Typical values are for T
J
= 25C, and represent the most likely parametric norm.
Note 8: Limits are guaranteed, by testing or correlation.

AC Electrical Characteristics

Note 9: Voltage Gain is the total output swing (20V) divided by the magnitude of the input signal required to produce that swing.
Note 10: For single-supply operation, the following conditions apply: V
+
= 5V, V
-
= 0V, V
CM
= 2.5V, V
OUT
= 2.5V. Pin 1 and Pin 8 (V
OS
Adjust pins) are each con-
nected to pin 4 (V
-
) to realize maximum output swing. This connection will increase the offset voltage.
Note 11: V
IN
= 10V step. For
5V supplies, V
IN
= 1V step.
Note 12: A military RETS electrical test specification is available on request.
