Using Custom Thermistors with the Temp-to-Bits Family

Logan Cummings - Sr. Applications Engineer Mar 29th 2017
The LTC2983, LTC2984, LTC2986 and LTC2986-1 Temp-to-Bits converters allow the use of custom sensors in addition to built-in standard types. This post focuses on custom thermistors and two ways of configuring the converter. Thermistors are resistive temperature sensors based on semiconductor materials. They are available in ...

Optimize Sense Resistor Cost and Accuracy for RTD Temp Measurement when Using LTC2983 Temp-to-Bits IC

Tom Domanski - Sr. Application Engineer Oct 19th 2015
The temperature measurement using a RTD, or a Thermistor, is really a measurement of resistance. RTDs and Thermistors change their resistance with temperature. Once the resistance of the probe is measured, and assuming that the Resistance as a function of temperature is known, the temperature of the probe can be calculated. ...

Using the LTC2983 with 18 2-wire RTDs

Tom Domanski - Sr. Application Engineer Sep 18th 2015
Introduction A number of times I have come accross system definitions calling for use of a large number of temperature probes. Large number is in the eye of the beholder, of course, but it still brings up a question of how many sensors can interface to the LTC2983, a device that after all boasts 20 analog inputs. Well, let's ...
