LM10
Operational Amplifier and Voltage Reference
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 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.
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
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.
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.
