Description

The DS1624 consists of a digital thermometer and 256 bytes of E2 memory. The thermometer provides 13-bit temperature readings which indicate the temperature of the device. The E2 memory allows a user to store frequency compensation coefficients for digital correction of crystal frequency due to temperature. Any other type of information may also reside in this user space.

Key Features

Temperature measurements require no external components Measures temperatures from -55°C to +125°C in 0.03125°C increments. Fahrenheit equivalent is -67°F to +257°F in 0.05625°F increments Temperature is read as a 13-bit value (two byte transfer) Converts temperature to digital word in 1 second (max) 256 bytes of E2 memory on board for storing information such as frequency compensation coefficients Data is read from/written via a 2-wire serial interface (open drain I/O lines) Applications include temperature-compensated crystal oscillators for test equipment and radio systems 8-pin DIP or SOIC packages
