LM10
Operational Amplifier and Voltage Reference
analog signals, delivering the processed signal on the same
line used to supply power. It is also suited for operation in a
wide range of voltage- and current-regulator applications,
from low voltages to several hundred volts, providing greater
precision than existing ICs.
General Description
The LM10 series are monolithic linear ICs consisting of a
precision reference, an adjustable reference buffer and an
independent, high quality op amp.
The unit can operate from a total supply voltage as low as
1.1V or as high as 40V, drawing only 270µA. A complemen-
tary output stage swings within 15 mV of the supply termi-
nals or will deliver 20 mA output current with 0.4V satu-
ration. Reference output can be as low as 200 mV.
This series is available in the three standard temperature
ranges, with the commercial part having relaxed limits. In
addition, a low-voltage specification (suffix “L”) is available in
the limited temperature ranges at a cost savings.
The circuit is recommended for portable equipment and is
completely specified for operation from a single power cell.
In contrast, high output-drive capability, both voltage and
current, along with thermal overload protection, suggest it in
demanding general-purpose applications.
Features
n input offset voltage: 2.0 mV (max)
n input offset current: 0.7 nA (max)
n input bias current: 20 nA (max)
n reference regulation: 0.1% (max)
n offset voltage drift: 2µV/˚C
n reference drift: 0.002%/˚C
The device is capable of operating in a floating mode, inde-
pendent of fixed supplies. It can function as a remote com-
parator, signal conditioner, SCR controller or transmitter for

Note 3: The maximum, operating-junction temperature is 150˚C for the LM10, 100˚C for the LM10B(L) and 85˚C for the LM10C(L). At elevated temperatures,
devices must be derated based on package thermal resistance.
Note 4: Internal thermal limiting prevents excessive heating that could result in sudden failure, but the IC can be subjected to accelerated stress with a shorted
output and worst-case conditions.

Note 7: This defines operation in floating applications such as the bootstrapped regulator or two-wire transmitter. Output is connected to the V terminal of the IC

and input common mode is referred to V (see typical applications). Effect of larger output-voltage swings with higher load resistance can be accounted for by adding
the positive-supply rejection error.
Note 8: Refer to RETS10X for LM10H military specifications.
Definition of Terms
Input offset voltage: That voltage which must be applied between the input terminals to bias the unloaded output in the linear
region.
Input offset current: The difference in the currents at the input terminals when the unloaded output is in the linear region.
Input bias current: The absolute value of the average of the two input currents.
Input resistance: The ratio of the change in input voltage to the change in input current on either input with the other grounded.
Large signal voltage gain: The ratio of the specified output voltage swing to the change in differential input voltage required to
produce it.
Shunt gain: The ratio of the specified output voltage swing to the change in differential input voltage required to produce it with
the output tied to the V+ terminal of the IC. The load and power source are connected between the V+ and V− terminals, and input
common-mode is referred to the V− terminal.
Common-mode rejection: The ratio of the input voltage range to the change in offset voltage between the extremes.
Supply-voltage rejection: The ratio of the specified supply-voltage change to the change in offset voltage between the
extremes.
Line regulation: The average change in reference output voltage over the specified supply voltage range.
Load regulation: The change in reference output voltage from no load to that load specified.
Feedback sense voltage: The voltage, referred to V−, on the reference feedback terminal while operating in regulation.
Reference amplifier gain: The ratio of the specified reference output change to the change in feedback sense voltage required
to produce it.
Feedback current: The absolute value of the current at the feedback terminal when operating in regulation.
Supply current: The current required from the power source to operate the amplifier and reference with their outputs unloaded
and operating in the linear range.

Application Hints
With heavy amplifier loading to V−, resistance drops in the
V− lead can adversely affect reference regulation. Lead re-
sistance can approach 1Ω. Therefore, the common to the
reference circuitry should be connected as close as possible
to the package.
