LM3911 Temperature Controller

General Description

The LM3911 is a highly accurate temperature measurement

perature range. Fabricated on a single monolithic chip, it

includes a temperature sensor, a stable voltage reference

and an operational amplifier.

The LM3911 uses the difference in emitter-base voltage of

transistors operating at different current densities as the ba-

sic temperature sensitive element. Since this output de-

pends only on transistor matching the same reliability and

stability as present op amps can be expected.

and/or control system for use over a 25 C to 85 C tem-

The output voltage of the LM3911 is directly proportional to

temperature in degrees Kelvin at 10 mV/ K. Using the inter-

The LM3911 is available in two package styles, a metal can

TO-46 and an 8-lead epoxy mini-DIP. In the epoxy package

all electrical connections are made on one side of the de-

vice allowing the other 4 leads to be used for attaching the

LM3911 to the temperature souce. The LM3911 is rated for

nal op amp with external resistors any temperature scale

factor is easily obtained. By connecting the op amp as a

comparator, the output will switch as the temperature trans-

verses the set-point making the device useful as an on-off

temperature controller.

operation over a 25 C to 85 C temperature range.

Features

An active shunt regulator is connected across the power

leads of the LM3911 to provide a stable 6.8V voltage refer-

ence for the sensing system. This allows the use of any

power supply voltage with suitable external resistors.

Uncalibrated accuracy 10 C

Internal op amp with frequency compensation

Linear output of 10 mV/ K (10 mV/ C)

Can be calibrated in degrees Kelvin, Celsius or

Fahrenheit

The input bias current is low and relatively constant with

temperature, ensuring high accuracy when high source im-

pedance is used. Further, the output collector can be re-

turned to a voltage higher than 6.8V allowing the LM3911 to

drive lamps and relays up to a 35V supply.

Output can drive loads up to 35V
