Overview
Description
LMT70YFQR is a Texas Instruments digital temperature sensor from the LMT70 family. The YFQR suffix denotes a specific package/configuration variant of the device. It provides a temperature measurement and delivers the result digitally via an I2C-compatible interface, enabling easy integration with microcontrollers and processors.
Key points:
- Interface: digital I2C output (temperature data registers)
- Power: designed for low power operation, suitable for battery-powered and embedded systems
- Temperature range: supports a broad operating range suitable for many applications
- Modes: typically supports single-shot and/or continuous conversion modes
- Packaging: offered in a compact package; exact variant identified by the YFQR code
Typical uses: MCU thermal monitoring, power electronics and battery-management systems, wearable and portable devices, automotive/industrial sensors.
For exact electrical specs, pinout, timing, and package dimensions, consult the TI LMT70YFQR datasheet.
