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. Acomplemen­tary output stage swings within 15 mV of the supply termi­nals or will deliver
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, inde­pendent of fixed supplies. It can function as a remote com­parator, 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 ad­dition, a low-voltage specification (suffix “L”) is available in
the limited temperature ranges at a cost savings.

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.

Note 2: 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 V

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 5: These specifications apply for V
for the standard part and 6.5V for the low voltage part. Normal typeface indicates 25˚C limits. Boldface type indicates limits and altered test conditions for
full-temperature-range operation; this is −55˚C to 125˚C for the LM10, −25˚C to 85˚C for the LM10B(L) and 0˚C to 70˚C for the LM10C(L). The specifications do
not include the effects of thermal gradients (τ
curves).

Note 6: For T
Note 7: This defines operation in floating applications such as the bootstrapped regulator or two-wire transmitter. Output is connected to the V
