ADT7422 ±0.1°C Accurate Digital Temperature Sensor

ADT7422 is ADI's first ±0.1°C accurate temperature sensor, that doesn't require any external circuitry for the operation. It can easily replace more complex and expensive solutions that use alternative sensor technologies such as thermistors or RTDs. In addition, high-precision silicon sensors (ICs) are preferred options for a range of emerging applications in the healthcare market such as vital signs monitoring instruments for clinical and home use.

Features

• ±0.1°C accuracy specification enables the end product to measure temperature with accuracy that was only possible for thermistors and RTDs
• Doesn't require external circuity: smaller, lower power, and lower cost than older sensing technologies
• Fully tested and calibrated solution: doesn't require system calibration to achieve desired ±0.1°C measurement precision

Applications

• Healthcare: vital signs monitoring, glucose meters, and incubators
• Consumer: vital signs monitoring
• Instrumentation: CJC, cold junction compensation for thermocouples, temperature control of cooling systems or industrial ovens, environmental sensing, water quality measurements
