LM6152/LM6154
Dual and Quad 75 MHz GBW Rail-to-Rail I/O Operational
Amplifiers
General Description
Features
Using patented circuit topologies, the LM6152/LM6154 pro-
vides new levels of speed vs. power performance in appli-
cations where low voltage supplies or power limitations pre-
viously 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 devices 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.
At VS = 5V, typical unless noted.

The LM6152/LM6154 can be driven by voltages that exceed
both power supply rails, thus eliminating concerns about
exceeding the common-mode voltage range. The rail-to-rail
output swing capability provides the maximum possible dy-
namic range at the output. This is particularly important
when operating on low supply voltages.
Applications
n Portable high speed instrumentation
n Signal conditioning amplifier/ADC buffers
n Barcode scanners
Operating on supplies from 2.7V to over 24V, the LM6152/
LM6154 is excellent for a very wide range of applications,
from battery operated systems with large bandwidth require-
ments to high speed instrumentation.

Application Information
The LM6152/LM6154 is ideally suited for operation with
about 10 kΩ (Feedback Resistor, RF) between the output
and the negative input terminal.
With RF set to this value, for most applications requiring a
close loop gain of 10 or less, an additional small compensa-
tion capacitor (CF) (see Figure 1) is recommended across RF
in order to achieve a reasonable overshoot (10%) at the
output by compensating for stray capacitance across the
inputs.
The optimum value for CF 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-
01235030
ing configuration and driving a 10 kΩ load have been tabu-
lated for reference:
FIGURE 1. Typical Inverting Gain Circuit AV = −1
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 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 ability to drive large capacitive loads without oscillating
functional removes this common problem.
In the non-inverting configuration, the LM6152/LM6154 can
be used for closed loop gains of +2 and above. In this case,
also, the compensation capacitor (CF) is recommended
across RF (= 10 kΩ) for gains of 10 or less.
To take advantage of these features, some ideas should be
kept in mind.
The LM6152/LM6154, capacitive loads do not lead to oscil-
lations, in all but the most extreme conditions, but they will
result in reduced bandwidth. They also cause increased
settling time.

Application Information (Continued)
The speed-up action adds stability to the system when driv-
ing large capacitive loads.
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
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.
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/LM6154, 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/LM6154 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.
