AD7814ARTZ-REEL

AD7814ARTZ-REEL Description

The AD7814ARTZ-REEL from Analog Devices Inc. is a high-precision, 10-bit resolution, digital temperature sensor with an SPI-compatible interface, designed for surface-mount applications. Operating within a 2.7V to 5.5V supply range, it delivers ±2°C accuracy (highest) over a -55°C to +125°C range, making it suitable for harsh environments. Packaged in a compact SOT-23-6 and supplied in Tape & Reel (TR), it is optimized for automated assembly. Though marked obsolete, it remains a reliable choice for legacy designs requiring local digital temperature sensing with low power consumption.

AD7814ARTZ-REEL Features
