The DS18S20+ from Maxim Integrated (Analog Devices) is a 1-Wire digital temperature sensor providing 9-bit Celsius measurements over -55C to +125C with +/-0.5C accuracy from -10 to +85C. The 1-Wire protocol requires only a single data line plus ground for communication and parasitic power. Each DS18S20 contains a unique 64-bit serial code allowing multiple devices on the same bus. Includes user-programmable alarm registers and temperature alarm search command. 750 ms typical conversion time.

The DS18S20+ integrates a bandgap temperature sensor, delta-sigma ADC, and 1-Wire interface. (1) Temperature: A bandgap PTAT sensor generates voltage proportional to absolute temperature, compared by delta-sigma ADC to produce 9-bit result with 0.5C resolution. (2) 1-Wire: Open-drain data line with strict timing. Master sends reset pulse, DS18S20 responds with presence pulse. ROM commands (Search, Match, Skip) address devices. Function commands (Convert T, Read/Write Scratchpad) control operation. (3) Parasitic Power: Internal diode charges parasite capacitor from data line high periods to power device during low periods.
