Product Overview
The TMP114 is a Texas Instruments digital temperature sensor for Sensor category designs using an I2C-compatible and SMBus-compatible digital interface. The device operates from a recommended 1.08 V to 1.98 V supply and supports an I/O voltage range of 0 V to 1.98 V on SCL and SDA. TMP114A, TMP114B, TMP114C, and TMP114D address variants use two-wire addresses 1001000, 1001001, 1001010, and 1001011 respectively.
Temperature measurement performance is specified across multiple ranges. TMP114 accuracy is ±0.2°C maximum from 20°C to 50°C at VDD = 1.8 V, ±0.3°C maximum from -10°C to 80°C at VDD = 1.8 V, and ±0.5°C maximum from -40°C to 125°C. TMP114N is specified at ±1°C maximum from -40°C to 125°C. Conversion output uses 16-bit resolution including the sign bit, with a 7.8125 m°C LSB.
The 4-pin PicoStar DSBGA/YMT package is 0.76 mm × 0.76 mm and 0.15 mm high. Package-related thermal data includes 168.7°C/W junction-to-ambient resistance, 1.0°C/W junction-to-case top resistance, 47.3°C/W junction-to-board resistance, and 0.16 mJ/°C thermal mass.
