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-
This series is available in the three standard temperature
ranges, with the commercial part having relaxed limits. In ad-
dition, a low-voltage specification (suffix “L”) is available in
the limited temperature ranges at a cost savings.

nals or will deliver 20 mA output current with 0.4V satura-
tion. Reference output can be as low as 200 mV.
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
