Dallas Semiconductor's temperature sensor chip, the DS600, is a ±0,5°C (max) accurate analog-output temperature sensor. The device comes factory calibrated and has a linear-voltage output characteristic, making it simple to use and implement in designs. The high accuracy and ease of use make it ideal for applications such as cold-junction compensation for high-precision thermocouples, replacing costly RTDs or existing accurate analog temperature sensors. The DS600 is also suited for medical, automotive, and industrial applications.
The DS600 measures its own temperature and outputs a voltage proportional to degrees centigrade. The voltage output has a +6,45 mV/°C (typ) sensitivity and a +509 mV d.c. offset, which allows negative temperatures to be easily measured and reported. The device's ±0,5°C (max) accuracy is rated over the 2,7 to 5,5 V operating voltage range and a -20°C to +100°C temperature range. Outside this range it is ±0,75°C (max) accurate to -40°C and +125°C.
The device also contains a thermostat function with a user-defined threshold and an internal comparator to ensure high-precision threshold detection. Power consumption is 140 µA (max) 2,5 µA in shutdown. The DS600 comes in an 8-pin microSOP-EP package.
