What this part is and where it fits
The Analog Devices TMP17FSZ is an analog, local temperature sensor that outputs a current proportional to temperature. Its output type is analog current, which means it delivers a current signal rather than a voltage — useful for driving long lines or feeding into a current-loop ADC input without extra signal conditioning. The sensor is rated for a -40°C to 105°C operating range and runs on a 4V to 30V supply, giving it flexibility across industrial control panels, HVAC equipment, and power-supply monitoring where the rail may not be tightly regulated.
Supply voltage range — why it matters
The 4V to 30V supply range is unusually wide. It lets you power the sensor directly from a 24V industrial supply rail or a 5V logic rail without a local regulator. That simplifies the BOM and reduces board area. Just watch the power dissipation at high supply voltages if the sensor is driving a heavy load — the current output itself is low, but the internal circuitry draws from the same rail.
Package and mounting
Housed in an 8-SOIC surface-mount package (3.90 mm width), the TMP17FSZ is a standard footprint that reflows easily and fits into automated assembly lines.
Lifecycle and sourcing
The TMP17FSZ is listed as Active and ROHS3 compliant.
