The ±1.75°C maximum accuracy sets the measurement uncertainty — if your system alarm threshold is 105°C, a reading of 103.25°C could already be at the limit. The internal sensor covers -40°C to +125°C, while the external sensor input reads a remote diode over the same span. This dual-sensor topology lets you monitor both the IC junction and a hot spot elsewhere on the board — a power inductor, a MOSFET heatsink, or a battery cell — through a single part. ## SST serial interface — not I²C, not SPI The output type is Simple Serial Transport (SST), a proprietary Analog Devices serial protocol. It is not I²C, SPI, or SMBus — the bus timing and command structure are specific to this family. If your existing firmware stack expects a standard two-wire interface, the SST bus requires a dedicated bit-bang or hardware SST controller. The 10-MSOP package (3.00 mm width, 0.118\" pitch) keeps the footprint small, but the interface choice is the real design constraint. Supply voltage is 3V to 3.6V, which maps cleanly onto a 3.3V rail. The part draws only the ADC and register bank current — no fan driver, no alarm output — so the thermal load on the board from the sensor itself is negligible. ## Active lifecycle — no LTB clock ticking The bulk package is the standard tube format. No board spin or firmware change is needed between the two.","metaTitle":"ADT7488AARMZ-RL Temp Sensor, ±1.75°C, SST, 10-MSOP","metaDescription":"Analog Devices ADT7488AARMZ-RL temperature monitoring system, ±1.75°C max accuracy, SST interface, -40°C to +125°C range, 10-MSOP.
