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-

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.
