It resolves temperature to 11 bits and reports ±2°C accuracy over the full -55°C to 100°C operating range, with a worst-case ±3°C at the extremes. The on-chip programmable limit feature lets the sensor assert an alarm without continuous host polling — useful for threshold-based monitoring in cold-chain, HVAC, or industrial equipment where the host controller polls a bus of sensors only when an out-of-range event occurs. ## Package and mounting The sensor ships in a standard TO-92-3 through-hole package (TO-226-3, TO-92-3). Three leads — ground, data, and VDD — fit a prototyping board or a soldered-in PCB hole pattern. ## Lifecycle and sourcing The DS1822+PAR carries an Active lifecycle status with ROHS3 compliance. The 1-Wire protocol and TO-92-3 footprint are widely second-sourced across the industry, but this exact order code is the factory-released variant with the +PAR suffix indicating the programmable alarm feature.","metaTitle":"DS1822+PAR Digital Temperature Sensor, TO-92-3","metaDescription":"DS1822+PAR digital local temperature sensor from Analog Devices. 11-bit resolution, 1-Wire interface, ±2°C accuracy, -55°C to 100°C range.

The key difference is resolution: the DS1822+PAR offers 11-bit resolution versus the DS18B20's 12-bit, and the accuracy specification differs. For applications where ±2°C is sufficient and the extra resolution bit is not needed, the DS1822+PAR is a functional drop-in replacement."},{"question":"Is DS1822+PAR compatible with Arduino?","answer":"Yes, the 1-Wire interface and 3V to 5.5V supply range are directly compatible with Arduino 5V logic.
