DS18S20
The Maxim Integrated DS18S20 is a digital thermometer providing 9-bit Celsius temperature
measurements. It measures temperatures from
−
55°C to +125°C with ±0.5°C accuracy from
−
10°C to
+85°C.
The DS18S20 is offered in parasite power and dedicated power modes. For this device, the use of parasite
power is not recommended for temperatures above 100°C. In applications in which such temperatures are
likely, it is strongly recommended to use a dedicated power mode DS18S20.
DS18B20
The DS18B20 and DS18S20 devices are very similar. The difference is that the DS18B20 gives 12 bits of
precision as compared to the DS18S20, which gives 9 bits of precision. The DS18B20 measures
temperatures from
−
55°C to +125°C with ±0.0625°C accuracy from
−
10°C to +85°C. Both devices have a
conversion time of 750ms.
