Temperature sensing with I²C bus integration
The DS7505S+ is a digital local temperature sensor from Analog Devices, outputting temperature data over an I²C-compatible serial interface with 11-bit resolution (0.125 °C per LSB).
Programmable limits and standby for system-level control
Built-in features include a programmable temperature limit with an output switch (OS) that asserts when the measured temperature crosses the threshold — useful as an overtemperature interrupt or fan-control trigger without polling the I²C bus. Shutdown and standby modes drop the quiescent current to microamps, letting the sensor sleep between periodic reads in battery-powered or thermal-throttling applications. The programmable resolution allows trading conversion time against noise — 11-bit is the default, but lower resolution speeds up the read cycle when fine granularity isn't needed.
Package, lifecycle, and compliance
Housed in an 8-pin SOIC (3.90 mm width) surface-mount package, supplied in tube format — the standard footprint suits reflow assembly with no special pad geometry.
