FEATURES
DESCRIPTIO
■
60µV Maximum Offset Voltage
The LT®6011/LT6012 op amps combine low noise and
high precision input performance with low power con-
sumption and rail-to-rail output swing.
■
300pA Maximum Input Bias Current
■
135µA Supply Current per Amplifier
■
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
accuracy over temperature and time. The 300pA maxi-
mum input bias current and 120dB minimum voltage gain
further maintain this precision over operating conditions.
■
120dB Minimum Voltage Gain, VS = ±15V
■
0.8µV/°C Maximum VOS Drift
14nV/√Hz Input Noise Voltage
■
■
2.7V to ±18V Supply Voltage Operation
■
Operating Temperature Range: –40°C to 85°C
■
The LT6011/LT6012 work on any power supply voltage
from 2.7V to 36V and draw only 135µA of supply current
ona5Vsupply.Theoutputswingstowithin40mVofeither
supply rail, making the amplifier a good choice for low
voltage single supply applications.

Note 1: Absolute Maximum Ratings are those beyond which the life if the
device may be impaired.
Note 6: This parameter is not 100% tested.
Note 7: Matching parameters are the difference between any two

series resistors. If the differential input voltage exceeds 10V, the input
current must be limited to less than 10mA.
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 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.

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
limitedtooperatingbetweenV–+1VandV+–1.2V.Exceed-
ing this common mode range will cause the gain to drop
to zero, however, no phase reversal will occur.
Theextremelylowinputbiascurrents(20pAtypical)allow
high accuracy to be maintained with high impedance
sources and feedback resistors. The LT6011/LT6012 low
input bias currents are obtained by a cancellation circuit
on-chip. This causes the resulting IB and IB to be
uncorrelated, as implied by the IOS specification being

Total Input Noise
TheLT6011/LT6012amplifiercontributesnegligiblenoise
to the system when driven by sensors (sources) with
impedance between 20kΩ and 1MΩ. Throughout this
range, total input noise is dominated by the 4kTRS noise
of the source. If the source impedance is less than 20kΩ,
the input voltage noise of the amplifier starts to contribute
withaminimumnoiseof14nV/√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:
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!
