What the ±2°C accuracy means for your thermal management loop
The MAX1617AMEE+ is a digital temperature sensor from Analog Devices that monitors both its own die temperature and an external diode-connected transistor, reporting readings over an SMBus interface. The 7-bit resolution gives a temperature step of roughly 1°C per LSB, which matches the accuracy spec — finer resolution wouldn't add meaningful precision here. The One-Shot and Standby Mode features let you power down the sensor between readings, cutting average current in battery-backed or low-power systems where continuous conversion isn't needed.
Supply voltage and interface compatibility
Operating from 3V to 5.5V, the sensor works directly off common 3.3V or 5V rails without an extra regulator. The SMBus output is a two-wire interface that shares the same bus as other SMBus devices — the address is set by the pin strapping, so multiple sensors can coexist on the same bus. The remote sensing channel uses a standard diode-connected transistor (like a 2N3904 or CPU's substrate PNP) placed at the measurement point. The local channel reads the die temperature inside the 16-QSOP package, useful for ambient or board-level temperature monitoring.
Package, mounting, and production status
Housed in a 16-SSOP (0.154", 3.90mm Width) package with surface mount termination, the MAX1617AMEE+ fits standard reflow assembly processes. Analog Devices lists this part as Active in production and ROHS3 compliant. Sourced through authorized distribution; availability confirmed at quote time.
