Rated for the full -55°C to 125°C operating range, it suits environmental monitoring in industrial controllers, telecom enclosures, and automotive cabin or under-hood zones where the extended temperature grade matters. The 9-bit resolution gives 0.5°C steps, and the typical accuracy of ±0.5°C at 0°C to 70°C (worst-case ±2°C across the full range) is tight enough for most system thermal management loops without external calibration. ## Package and mounting 8-pin SOIC (0.209\" body width, 5.30 mm wide), surface-mount. Tube shipment. ## Lifecycle and sourcing No second-source alternate is listed.","metaTitle":"DS1620S+ Digital Temperature Sensor, ±0.5°C Accuracy, 8-SOIC","metaDescription":"Maxim Integrated DS1620S+ digital temperature sensor, ±0.5°C accuracy, -55°C to 125°C range, 2.7V-5.5V supply, 3-wire interface.
