Frequently Asked Questions
What is the accuracy and temperature range of the TMP112AQDRLRQ1?
The TMP112AQDRLRQ1 provides a maximum accuracy of ±0.5°C over the full operating range of -40°C to +125°C. It delivers 12-bit resolution with a temperature resolution of 0.0625°C, making it suitable for precision automotive and industrial temperature measurement applications.
What interface does the TMP112AQDRLRQ1 use and what is the supply voltage?
The TMP112AQDRLRQ1 uses an I2C/SMBus compatible digital interface supporting Standard Mode (100kHz) and Fast Mode (400kHz). It operates from a supply voltage of 1.4V to 3.6V, enabling direct connection to low-voltage microcontrollers and application processors without level shifting.
Is the TMP112AQDRLRQ1 qualified for automotive applications?
Yes, the TMP112AQDRLRQ1 is AEC-Q100 Grade 1 qualified, meeting stringent automotive reliability standards. The 'Q1' suffix in the part number designates automotive qualification, making it suitable for under-hood, HVAC, battery management, and other automotive end equipment requiring long-term reliability.
What package does the TMP112AQDRLRQ1 come in and how small is it?
The TMP112AQDRLRQ1 comes in a 6-pin SOT563 (WSON) surface-mount package measuring just 1.6mm × 1.2mm × 0.6mm. This ultra-compact footprint is ideal for space-constrained PCB designs in wearables, automotive modules, and portable industrial sensors.
What are common alternatives or substitutes for the TMP112AQDRLRQ1?
Common alternatives include the TMP102 (standard commercial grade I2C sensor in SOT563), TMP112 (non-automotive version), and the LM75 series from Texas Instruments or NXP. For pin-compatible automotive-grade alternatives, the TMP1075-Q1 offers extended features. Always verify package, accuracy, and qualification grade before substitution.
