FEATURES
DESCRIPTIO
TheLT®6013andLT6014opampscombinelownoiseand
high precision input performance with low power con-
sumption and rail-to-rail output swing. The amplifiers are
stable in a gain of 5 or more and feature greatly improved
CMRR and PSRR versus frequency compared to other
precision op amps.
■
35µV Maximum Offset Voltage (LT6013A)
Low 1/f Noise: 200nVP-P (0.1Hz to 10Hz)
■
40nVRMS (0.1Hz to 10Hz)
■
Low White Noise: 9.5nV/√Hz (1kHz)
■
Rail-to-Rail Output Swing
■
145µA Supply Current per Amplifier
■
250pA Maximum Input Bias Current (LT6013A)
Input offset voltage is factory-trimmed to less than 35µV.
The low drift and excellent long-term stability ensure a
high accuracy over temperature and time. The 250pA
maximum input bias current and 120dB minimum voltage
gain further maintain this precision over operating
conditions.
■
AV ≥5 Stable; Up to 500pF CLOAD
■
0.2V/µs Slew Rate
■
1.4MHz Gain Bandwidth Product
■
120dB Minimum Voltage Gain, VS = ±15V
■
0.8µV/°C Maximum VOS Drift
■
2.7V to ±18V Supply Voltage Operation
■
■
The LT6013 and LT6014 operate from any supply voltage
from 2.7V to 36V and draw only 145µA of supply current
per amplifier on a 5V supply. The output swings to within
40mV of either supply rail, making the amplifiers very
useful for low voltage single supply operation.
Operating Temperature Range: –40°C to 85°C
Available in SO-8 and Space Saving 3mm × 3mm

U
APPLICATIO S
■
The amplifiers are fully specified at 5V and ±15V supplies
and from –40°C to 85°C. The single LT6013 and dual
LT6014 are both available in SO-8 and space saving
3mm × 3mm DFN packages. For unity gain stable ver-
sions, refer to the LT6010 and LT6011 data sheets.

ELECTRICAL CHARACTERISTICS

device may be impaired.
Note 7: Matching parameters are the difference between the two
amplifiers. ∆CMRR and ∆PSRR are defined as follows: (1) CMRR and
PSRR are measured in µV/V for the individual amplifiers. (2) The
difference between matching amplifiers is calculated in µV/V. (3) The
result is converted to dB.
Note 2: The inputs are protected by back-to-back diodes and internal
series resistors. If the differential input voltage exceeds 10V, the input
current must be limited to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum ratings.
Note 4: The LT6013C/LT6014C and LT6013I/LT6014I are guaranteed
functional over the operating temperature range of –40°C to 85°C.
Note 5: The LT6013C and LT6014C are guaranteed to meet the specified
performance from 0°C to 70°C and are designed, characterized and
expected to meet specified performance from –40°C to 85°C but is not
tested or QA sampled at these temperatures. The LT6013I and LT6014I are
guaranteed to meet specified performance from –40°C to 85°C.

3. Findthedifferentialvoltagethatwouldappearacross
the two inputs of the op amp.
The LT6013 and LT6014 amplifiers are optimized for the
lowest possible noise and smallest package size, and are
intentionally decompensated to be stable in a gain con-
figuration of 5 or greater. Do not connect the amplifiers in
a gain less than 5 (such as unity-gain). For a unity-gain
stable amplifier with similar performance though slightly
higher noise and lower bandwidth, see the LT6010 and
LT6011/LT6012 datasheets.
4. The ratio of the output voltage to the input voltage is
the gain that the op amp “sees”. This ratio must be
5 or greater.
Do not place a capacitor bigger than 200pF between the
outputtotheinvertinginputunlessthereisa5timeslarger
capacitor from that input to AC ground. Otherwise, the op
amp gain would drop to less than 5 at high frequencies,
and the stability of the loop would be compromised.
Figure1showssimpleinvertingandnon-invertingopamp
configurations and indicates how to achieve a gain of 5 or
greater. For more general feedback networks, determine
the gain that the op amp “sees” as follows:
The LT6013 and LT6014 can be used in lower gain
configurations when an impedance is connected between
the op amp inputs. Figure 2 shows inverting and non-
inverting unity gain connections. The RC network across
the op amp inputs results in a large enough noise gain at
high frequencies, thereby ensuring stability. At low fre-
quencies, the capacitor is an open circuit so the DC
precision (offset and noise) remains very good.
1. Suppose the op amp is removed from the circuit.
2. Applyasmall-signalvoltageattheoutputnodeofthe

Preserving Input Precision
Preserving the input accuracy of the LT6013 and LT6014
requires that the applications circuit and PC board layout
do not introduce errors comparable to or greater than the
10µVtypicaloffsetoftheamplifiers.Temperaturedifferen-
tials across the input connections can generate thermo-
couple voltages of 10’s of microvolts so the connections
totheinputleadsshouldbeshort,closetogetherandaway
fromheatdissipatingcomponents.Aircurrentsacrossthe
board can also generate temperature differentials.
Input Common Mode Range
The LT6013/LT6014 output is able to swing close to each
power supply rail (rail-to-rail out), but the input stage is
limitedtooperatingbetweenV–+1VandV+–1.2V.Exceed-
ing this common mode range will cause the gain to drop
to zero; however, no phase reversal will occur.
Total Input Noise
Theextremelylowinputbiascurrentsallowhighaccuracy
to be maintained with high impedance sources and feed-
backresistors.TheLT6013andLT6014lowinputbiascur-
rents are obtained by a cancellation circuit on-chip. This
The LT6013 and LT6014 amplifiers contribute negligible
noisetothesystemwhendrivenbysensors(sources)with
impedance between 10kΩ and 1MΩ. Throughout this
range, total input noise is dominated by the 4kTRS noise
of the source. If the source impedance is less than 10kΩ,
the input voltage noise of the amplifier starts to contribute
withaminimumnoiseof9.5nV/√Hzforverylowsourceim-
pedance. If the source impedance is more than 1MΩ, the
input current noise of the amplifier, multiplied by this high
impedance, starts to contribute and eventually dominate.
Total input noise spectral density can be calculated as:
causes the resulting IB+ and IB to be uncorrelated, as
–
impliedbytheIOS specificationbeingcomparabletoIB.Do
not try to balance the input resistances in each input lead;
instead keep the resistance at either input as low as pos-
sible for maximum accuracy.
Leakage currents on the PC board can be higher than the
inputbiascurrent.Forexample,10GΩofleakagebetween
a 15V supply lead and an input lead will generate 1.5nA!

where en = 9.5nV/√Hz , in = 0.15pA/√Hz and RS is the total

Input Protection
Capacitive Loads
TheLT6013/LT6014featureson-chipback-to-backdiodes
between the input devices, along with 500Ω resistors in
series with either input. This internal protection limits the
input current to approximately 10mA (the maximum al-
lowed) for a 10V differential input voltage. Use additional
external series resistors to limit the input current to 10mA
in applications where differential inputs of more than 10V
The LT6013 and LT6014 can drive capacitive loads up to
500pF at a gain of 5. The capacitive load driving capability
increases as the amplifier is used in higher gain configu-
rations. A small series resistance between the output and
the load further increases the amount of capacitance that
the amplifier can drive.
