The DS18B20 digital thermometer can also operate in parasitic power mode, drawing power directly from the signal line, thereby eliminating the need for an external power supply.
. Each DS18B20 has a globally unique 64-bit serial code, allowing multiple DS18B20s to be connected to the same single bus for networking. A single microcontroller can control numerous DS18B20s distributed over a large area, this networking approach is particularly suitable for applications such as HVAC environmental control, building and equipment temperature monitoring, grain condition monitoring, industrial temperature measurement, and process monitoring and control.
.User-selectable temperature resolution from 9 to 12 bits.
.Temperature conversion speed is less than 400 ms at the highest 12-bit resolution.
.User-programmable, non-volatile temperature alarm settings.
.The alarm search command identifies and flags devices whose temperature exceeds the programmed limits
.Excellent ESD protection capability: HBM 8000V, MM 800V.
Available packages include the surface-mount MSOP8, SOP8, and the 3-pin TO-92, TO-92s.
