  • The STLM75 is a high-precision digital CMOS temperature sensor IC with a sigma-delta temperature-to-digital converter and an I2C-compatible serial digital interface. It is targeted for general applications such as personal computers, system thermal management, electronics equipment, and industrial controllers, and is packaged in the industry standard 8-lead TSSOP and SO8 packages.

    The device contains a band gap temperature sensor and 9-bit ADC which monitor and digitize the temperature to a resolution up to 0.5 °C. The STLM75 is typically accurate to (±3 °C - max) over the full temperature measurement range of –55 °C to 125 °C with ±2 °C accuracy in the –25 °C to +100 °C range. The STLM75 is pin-for-pin and software compatible with the LM75B.
    The STLM75 is specified for operating at supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the supply current is typically (125 μA).
    The on-board sigma-delta analog-to-digital converter (ADC) converts the measured temperature to a digital value that is calibrated in degrees centigrade; for Fahrenheit applications a lookup table or conversion routine is required.
    The STLM75 is factory-calibrated and requires no external components to measure temperature.

    Key Features

    • Measures temperatures from –55°C to +125°C (–67°F to +257°F)
      • ±0.5°C (typ) accuracy
      • ±2°C (max) accuracy from –25°C to +100°C
    • Low operating current: 125 μA (typ)
    • No external components required
    • 2-wire I2C/SMBus-compatible serial interface
      • Supports bus time-out feature
      • Selectable bus address allows connection of up to eight devices on the bus
    • Wide power supply range-operating voltage range: 2.7 V to 5.5 V
    • Conversion time is 150 ms (max)
    • Programmable temperature threshold and hysteresis set points
    • Pin- and software-compatible with LM75 (drop-in replacement)
    • Power-up defaults permit standalone operation as a thermostat
    • Shutdown mode to minimize power consumption
    • Output pin (open drain) can be configured for interrupt or comparator/thermostat mode (dual purpose event pin)
    • Packages:
      • SO8
      • MSOP8 (TSSOP8)
