The DS1620 is a complete digital thermometer on a chip, capable of replacing the normal combination of temperature sensor and analog-to-digital converter in most applications.

It can measure temperature in units of 0.5° Centigrade (C) from -55° C to +125° C. (In Fahrenheit (°F), units of 0.9° F and a range of -67° F to +257° F.)

The DS1620 can also operate as a standalone thermostat. A temporary connection to a controller establishes the mode of operation and high/low-temperature set points.

Thereafter, the chip independently controls three outputs: T (high), which goes active at temperatures above the high-temperature set point; T (low), active at temperatures below the set point; and T (com), which goes active at temperatures above the high set point, and stays active until the temperature drops below the low set point.

Features:

  • Measures temperature within +/- 0.5°C error
  • Converts temperature to digital word in 750 ms
  • Interfaces with any Parallax microcontroller

Key Specifications:

  • Power requirements: 2.7 to 5.5 VDC
  • Communication: Three-Wire Serial Connection
  • Dimensions: 0.24 x 0.35 in (0.62 x 0.9 cm)
  • Operating temp range: -67 to +257 °F (-55 to +125 °C)
