Description
The STDS75 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 (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 (see Figure 2 on page 8).

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: 125 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 150 ms (max)
■ Programmable temperature threshold and
   hysteresis set points
■ Wide power supply range-operating voltage
   range: 2.7 V to 5.5 V
■ Pin- and software-compatible with DS75 (dropin replacement)
■ 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)
