Rail-to-Rail Output Swing
Input offset voltage is trimmed to less than 60µV. The low
drift and excellent long-term stability guarantee a high ac-
curacy over temperature and time. The 300pA maximum
inputbiascurrentand120dBminimumvoltagegainfurther
maintain this precision over operating conditions.

2.7V to 18V Supply Voltage Operation
Operating Temperature Range: –40°C to 85°C
Space Saving 3mm × 3mm DFN Package
The LT6011/LT6012 work on any power supply voltage
from 2.7V to 36V and draw only 135µA of supply current
on a 5V supply. The output swings to within 40mV of
either supply rail, making the amplifier a good choice for
low voltage single supply applications.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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: Both the LT6011C/LT6012C and LT6011I/LT6012I are guaranteed
functional over the operating temperature range of –40°C to 85°C.
Note 5: The LT6011C/LT6012C are guaranteed to meet the specified
performance from 0°C to 70°C and is 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 LT6011I/LT6012I are
guaranteed to meet specified performance from –40°C to 85°C.
Note 6: This parameter is not 100% tested.
Note 7: Matching parameters are the difference between any 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.

typical offset of the amplifiers. Temperature differentials
across the input connections can generate thermocouple
voltages of 10’s of microvolts so the connections to the
input leads should be short, close together and away from
heatdissipatingcomponents.Aircurrentsacrosstheboard
can also generate temperature differentials.
The LT6011/LT6012 feature on-chip back-to-back diodes
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
areexpected. Forexample, a1kresistorinserieswitheach
input provides protection against 30V differential voltage.
The extremely low input bias currents (20pA typical) al-

sources and feedback resistors. The LT6011/LT6012 low
input bias currents are obtained by a cancellation circuit
Input Common Mode Range
The LT6011/LT6012 output is able to swing close to each
power supply rail (rail-to-rail out), but the input stage
is limited to operating between V + 1V and V – 1.2V.
Exceeding this common mode range will cause the gain
to drop to zero, however, no phase reversal will occur.

The LT6011/LT6012 amplifier contributes negligible noise
to the system when driven by sensors (sources) with
impedance between 20kΩ and 1MΩ. Throughout this
Leakage currents on the PC board can be higher than the
input bias current. For example, 10GΩ of leakage between
a 15V supply lead and an input lead will generate 1.5nA!

the input voltage noise of the amplifier starts to contribute

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:
A small series resistance between the output and the
load further increases the amount of capacitance that the
amplifier can drive.
Rail-to-Rail Operation
The LT6011/LT6012 outputs can swing to within millivolts
of either supply rail, but the inputs can not. However, for
most op amp configurations, the inputs need to swing
less than the outputs. Figure 1 shows the basic op amp
configurations, lists what happens to the op amp inputs
and specifies whether or not the op amp must have rail-
to-rail inputs. Select a rail-to-rail input op amp only when
