LM10QML
Operational Amplifier and Voltage Reference
parator, signal conditioner, SCR controller or transmitter for
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 is a monolithic linear IC consisting of a precision
reference, an adjustable reference buffer and an indepen-
dent, 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 terminals
or will deliver ±20 mA output current with ±0.4V saturation.
Reference output can be as low as 200 mV.
Features
Input offset voltage: 2.0 mV (max)

Input offset current: 0.7 nA (max)
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 cur-
rent, along with thermal overload protection, suggest it in
demanding general-purpose applications.
Input bias current: 20 nA (max)
Reference regulation: 0.1% (max)
Offset voltage drift:ꢀ2μV/°C
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-

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package
junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/
θ
JA or the number given in the Absolute Maximum Ratings, whichever is lower..
Note 3: The Input voltage can exceed the supply voltages provided that the voltage from the input to any other terminal does not exceed the maximum differential
-
input voltage and excess dissipation is accounted for when VI< VS
.
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 5: Guaranteed parameter, not tested,
Note 6: This defines operation in floating applications such as the bootstrapped regulator or two-wire transmitter. Output is connected to the VS+ terminal of the
IC and input common mode is referred to VS- (see typical applications). Effect of larger output-voltage swings with higher load resistance can be accounted for
by adding the positive-supply rejection error.

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 VS+ terminal of the IC. The load and power source are connected between the VS+ and VS- terminals, and
input common-mode is referred to the VS- 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 VS , 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.

-
With heavy amplifier loading to VS , resistance drops in the

to the package.
-
VS lead can adversely affect reference regulation. Lead re-
