 LM3911N Temperature Controller Integrated Circuit 

Manufactured by National Semiconductor

General Description

The LM3911 is a highly accurate temperature measurement and/or control system for use over a -25’C to +85’C temperature range. 

Fabricated on a single monolithic chip, it includes a temperature sensor, a stable voltage reference and an operational amplifier.

The output voltage of the LM3911 is directly proportional to temperature in degrees Kelvin at 10 mV/’K. Using the internal 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 transverses the set-point making the device useful as an on-off temperature controller.

Features
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
Output can drive loads up to 35V
Internal stable voltage reference

These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however in pristine condition still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee.
