LM6152/LM6154
Dual and Quad High Speed/Low Power 75 MHz GBW
Rail-to-Rail I/O Operational Amplifiers
General Description
Features
=
At VS 5V, Typ unless noted
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 de-
vices increases with increasing input differential voltage,
thus allowing the device to handle capacitive loads while
maintaining large signal amplitude.
n Greater than Rail-to-Rail Input CMVR −0.25V to 5.25V
n Rail-to-Rail Output Swing 0.01V to 4.99V
n Wide Gain-Bandwidth: 75 MHz 100 kHz
@
n Slew Rate:
Small signal 5V/µs
Large signal 45V/µs
n Low supply current 1.4mA/amplifier
n Wide supply range 2.7V to 24V
n Fast settling time of 1.1µs for 2V step (to 0.01%)
n PSRR 91 dB
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 oper-
ating on low supply voltages.
n CMRR 84 dB
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 LM6152/54
is excellent for a very wide range of applications, from bat-
tery operated systems with large bandwidth requirements to
high speed instrumentation.

Typical Performance
Characteristics (Continued)
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.
Total Harmonic Distortion
vs. Frequency
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.
DS012350-31
The LM6152/6154, capacitive loads do not lead to oscilla-
tions, in all but the most extreme conditions, but they will re-
sult in reduced bandwidth. They also cause increased set-
tling time.
Application Information
The LM6152/6154 is ideally suited for operation with about
10kΩ (Feedback Resistor, RF) between the output and the
negative input terminal.
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 ampli-
tude. 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 30V/µs.
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 out-
put 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 depen-
dant on the supply voltage, output driving load, and the oper-
ating gain. Below, some typical values used in an inverting
configuration and driving a 10kΩ load have been tabulated
for reference:

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.

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 (CF) is recommended
=
across RF
(
10 kΩ) for gains of 10 or less.
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.
