TMP101NA/250 – TEXAS INSTRUMENTS

The TMP101NA/250 is a precision digital temperature sensor from Texas Instruments, packaged in a small 8-pin SOIC (Small Outline Integrated Circuit). Unlike broader TMP101 offerings, the “/250” suffix denotes a specific calibration and testing procedure resulting in enhanced accuracy within a narrower operating temperature range, typically optimized for applications between -40°C and +85°C. It operates from a 2.7V to 5.5V supply voltage, consuming a mere 10µA typical operating current. The device features a 12-bit resolution, providing temperature readings with a resolution of 0.0625°C, and communicates via a simple I2C interface, simplifying integration into microcontroller-based systems._x000D_

Its key advantage lies in its combination of high accuracy and low power consumption, making it ideal for battery-powered applications requiring precise temperature monitoring. Common use cases include portable medical devices, industrial sensors requiring accurate temperature compensation, and precision data acquisition systems where minimal power draw is crucial. The enhanced accuracy of the TMP101NA/250, compared to broader TMP101 variants, eliminates the need for extensive on-chip calibration routines, reducing software complexity and improving overall system stability. Note that while the wider TMP101 family offers a broader operating temperature range, the TMP101NA/250 prioritizes accuracy within a defined range making it a superior choice when precision within that range is paramount.
