3 Conclusion

There are a variety of replacement options for RTD applications. Depending on specific system needs, a digital temperature sensor such as the TMP116, TMP117, or TMP1826 can increase accuracy while keeping printed circuit board costs and complexity low. For other systems, the TMP61 silicon-based linear thermistor can be easily integrated using a current or voltage biasing source from an already-existing RTD design. The high accuracy and fast response time of these semiconductor temperature sensors are key performance differentiators that allow these devices to replace expensive RTD systems in real-time control applications. In applications where milliseconds can make or break system stability, TI enables the sensing, processing, control and communication necessary to implement and optimize real-time control.
