Summary description
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 (see Figure 1 on page 7). 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.

FEATUREs
■ Measures temperatures from –55°C to +125°C
   (–67°F to +257°F)
   – ±2°C accuracy from –25°C to
      +100°C (max)
■ Low operating current: 125µA (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
