  • The STTS75 is a high-precision CMOS (digital) temperature sensor IC with a delta-sigma analog-to-digital (ADC) 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 MSOP(TSSOP) and SO8 packages.

    The device contains a band gap temperature sensor and programmable 9- to 12-bit ADC which monitor and digitize the temperature to a resolution up to 0.0625 °C. The STTS75 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. At power-up, the STTS75 defaults to 9-bit resolution for software compatibility with the STLM75.
    The STTS75 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 (75 μA).
    The onboard delta-sigma analog-to-digital converter (ADC) converts the measured temperature to a digital value that is calibrated in °C; for Fahrenheit applications a lookup table or conversion routine is required.
    The STTS75 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: 75 μA (typ)
    • No external components required
    • 2-wire I2C/SMBus-compatible serial interface
      • Selectable serial bus address allows connection of up to eight devices on the same bus
    • Thermometer resolution is user-configurable from 9 (default) to 12 bits (0.5 °C to 0.0625 °C)
    • 9-bit conversion time is 45 ms (typ)
    • Programmable temperature threshold and hysteresis set points
    • Wide power supply range-operating voltage range: 2.7 V to 5.5 V
    • Power saving one-shot temperature measurement
    • Power-up defaults permit standalone operation as thermostat
    • Shutdown mode to minimize power consumption
    • Separate open drain output pin operates as an interrupt or comparator/thermostat output (dual purpose event pin)
    • Packages:
      • SO8
      • MSOP8 (TSSOP8)
