LM6152/LM6154
Dual and Quad 75 MHz GBW Rail-to-Rail I/O Operational
Amplifiers
General Description
Using patented circuit topologies, the LM6152/54 provides
new levels of speed vs. power performance in applications
where low voltage supplies or power limitations previously
made compromise necessary. With only 1.4 mA/amplifier
supply current, the 75 MHz gain bandwidth of this device
supports new portable applications where higher power de-
vices unacceptably drain battery life. The slew rate of the
devices increases with increasing input differential voltage,
thus allowing the device to handle capacitive loads while
maintaining large signal amplitude.
The LM6152/54 can be driven by voltages that exceed both
power supply rails, thus eliminating concerns about exceed-
ing the common-mode voltage range. The rail-to-rail output
swing capability provides the maximum possible dynamic
range at the output. This is particularly important when op-
erating on low supply voltages.
Operating on supplies from 2.7V to over 24V, the LM6152/54
is excellent for a very wide range of applications, from bat-
tery operated systems with large bandwidth requirements to
high speed instrumentation.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5 kΩin series with 100 pF.
Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C.
Note 4: The maximum power dissipation is a function of TJ(MAX) ,θJA, and TA. The maximum allowable power dissipation at any ambient temperature
is PD=(T

Application Information
The LM6152/6154 is ideally suited for operation with about
10 kΩ(Feedback Resistor, R
F
) between the output and the
negative input terminal.
With R
F
set to this value, for most applications requiring a
close loop gain of 10 or less, an additional small compensa-
tion capacitor (C
F
) (see Figure 1) is recommended across R
F
in order to achieve a reasonable overshoot (10%) at the
output by compensating for stray capacitance across the
inputs.
The optimum value for C
F
can best be established experi-
mentally with a trimmer cap in place since its value is de-
pendant on the supply voltage, output driving load, and the
operating gain. Below, some typical values used in an invert-
ing configuration and driving a 10 kΩload have been tabu-
lated for reference:

−100 None 0.797

−1 2.2 6.6
−10 4.7 2.2
−100 None 0.962
In the non-inverting configuration, the LM6152/6154 can be
used for closed loop gains of +2 and above. In this case,
also, the compensation capacitor (C
F
) is recommended
across R
F
(= 10 kΩ) for gains of 10 or less.
Because of the unique structure of this amplifier, when used
at low closed loop gains, the realizable BW will be much less
than the GBW product would suggest.
The LM6152/6154 brings a new level of ease of use to op
amp system design.
The greater than rail-to-rail input voltage range eliminates
concern over exceeding the common-mode voltage range.
The rail-to-rail output swing provides the maximum possible
dynamic range at the output. This is particularly important
when operating on low supply voltages.
The high gain-bandwidth with low supply current opens new
battery powered applications where higher power consump-
tion previously reduced battery life to unacceptable levels.
The ability to drive large capacitive loads without oscillating
functional removes this common problem.
To take advantage of these features, some ideas should be
kept in mind.
The LM6152/6154, capacitive loads do not lead to oscilla-
tions, in all but the most extreme conditions, but they will
result in reduced bandwidth. They also cause increased
settling time.
Unlike most bipolar op amps, the unique phase reversal
prevention/speed-up circuit in the input stage, caused the
slew rate to be very much a function of the input pulse
01235030

Application Information (Continued)
amplitude. This results in a 10 to 1 increase in slew rate
when the differential input signal increases. Large fast
pulses will raise the slew-rate to more than 30 V/µs.
The speed-up action adds stability to the system when driv-
ing large capacitive loads.
A conventional op amp exhibits a fixed maximum slew-rate
even though the differential input voltage rises due to the
lagging output voltage. In the LM6152/6154, increasing lag
causes the differential input voltage to increase but as it
does, the increased slew-rate keeps the output following the
input much better. This effectively reduces phase lag. As a
result, the LM6152/6154 can drive capacitive loads as large
as 470 pF at gain of 2 and above, and not oscillate.
Capacitive loads decrease the phase margin of all op amps.
This can lead to overshoot, ringing and oscillation. This is
caused by the output resistance of the amplifier and the load
capacitance forming an R-C phase shift network. The
LM6152/6154 senses this phase shift and partly compen-
sates for this effect.
