Product details

Digital temperature sensor in a through-hole DIP

The DS1631+ from Analog Devices is a digital local temperature sensor that communicates over an I²C bus and delivers 11-bit resolution. It is housed in an 8-pin PDIP package for through-hole mounting, making it a natural fit for breadboard prototyping, legacy PCB layouts, or applications where socketed installation is preferred over surface-mount. Key features include programmable temperature limits with an output switch, programmable resolution, a one-shot conversion mode for single-read operations, and a standby mode to reduce supply current between measurements. Accuracy is rated at ±0.5°C typical and ±2°C maximum over the full -55°C to 125°C operating range, which covers industrial, automotive under-hood, and outdoor telecom enclosure environments.

Sourcing and lifecycle — active, no obsolescence concern

The DS1631+ carries an Active product status and is RoHS3 compliant. There is no end-of-life notice or last-time-buy window to track. For BOM planning, this part can be specified into new designs without a near-term requalification risk.

Frequently asked questions

What is the accuracy of the DS1631+?

Typical accuracy is ±0.5°C, with a maximum of ±2°C across the full -55°C to 125°C temperature range.

What is the closest pin-compatible equivalent to the DS1631+?

Within the same family, the DS1631 is the base part number without the plus suffix. The DS1631+ indicates RoHS3 compliance and lead-free construction. Pin-compatible alternatives from other manufacturers are not listed in the available records; verify footprint and I²C address compatibility against your layout.
