High-Voltage Amplifier Extends Coulomb Counter Range to +/-270V
Jan 22nd 2016
Introduction
A coulomb counter can measure charge that flows into or out of a battery. Small, dedicated devices such as LTC2941 or LTC2943 can directly interface with low to medium battery voltages, up to about 20V. You can extend the input operating range of the measurement circuit by using a high-voltage amplifier as a level ...
Power Supply Sequencing Simplified
Dec 7th 2015
Design Note 1037: Introduction
Designing a multiple power supply system is challenging. The power supply designer’s workload multiplies with each additional supply rail. The designer must consider the dynamic environment of coordinated power supply sequencing and timing, generating power-on reset, monitoring for faults ...
Optimize Sense Resistor Cost and Accuracy for RTD Temp Measurement when Using LTC2983 Temp-to-Bits IC
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
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 ...
System Monitor with Instrumentation-Grade Accuracy Used to Measure Relative Humidity
Jan 1st 2013
Because much can be deduced about a physical system by measuring temperature, it is by far the most electronically measured physical parameter. Selecting a temperature sensor involves balancing accuracy requirements, durability, cost and compatibility with the measured medium. For instance, because of its low cost, a small-signal ...
