Key Features
- Linear 10mV/°C analog output provides a ground-referenced voltage directly compatible with MCU ADC inputs, eliminating the need for I2C or SPI firmware overhead
- ±2.5°C maximum accuracy with integrated short-circuit protection ensures reliable temperature readings in cost-sensitive industrial and consumer designs
- Tiny SOT-23 package measuring 2.92mm x 1.3mm x 0.95mm enables drop-in temperature sensing on space-constrained boards with a three-pin footprint
Applications
The TMP235A2DBZR is ideal for simple board temperature monitoring in industrial equipment, power supplies, and consumer electronics where a microcontroller ADC reads a linear voltage proportional to temperature without any digital communication protocol. Its 10mV/°C gain and ground-referenced output make it easy to interface to comparator-based thermostat circuits and fan control systems. The compact SOT-23 package and short-circuit protection make it a robust and cost-effective temperature sensing solution for high-volume production designs.
