TMP102AIDRLR Texas Instruments Digital Temperature Sensor I2C/SMBus ±0.5°C Accuracy SOT-563
TMP102AIDRLR Product Overview
The TMP102AIDRLR is a high-accuracy, low-power digital temperature sensor from Texas Instruments, housed in a 1.6mm × 1.6mm SOT-563 package that is 68% smaller than the SOT-23 footprint. Designed as an ideal replacement for NTC/PTC thermistors in high-accuracy applications, the TMP102AIDRLR offers ±0.5°C accuracy without requiring calibration or external component signal conditioning. The TMP102AIDRLR integrates an on-chip 12-bit ADC providing resolutions down to 0.0625°C, SMBus/two-wire/I2C interface compatibility, and operation over a 1.4V to 3.6V supply range, making the TMP102AIDRLR ideal for portable electronics, power-supply temperature monitoring, battery management, and industrial control applications.

FAQ
Q: How is the accuracy performance of the TMP102AIDRLR?
A: The TMP102AIDRLR offers ±0.5°C typical accuracy without calibration. Maximum error is ±2.0°C from -25°C to 85°C, and ±3.0°C over the full -40°C to 125°C range.
Q: How does the TMP102AIDRLR connect to a microcontroller?
A: The TMP102AIDRLR communicates via the I2C/SMBus two-wire serial interface. SCL and SDA pins are open-drain and require external pull-up resistors. The ADD0 pin configures the device address, supporting up to 4 devices on a single bus.
Q: How is the power consumption of the TMP102AIDRLR?
A: The TMP102AIDRLR's maximum quiescent current is only 7.5μA in active mode and 0.35μA in shutdown mode, ideal for battery-powered or power-sensitive portable applications.
