The Analog Devices TMP17 is a monolithic temperature transducer that outputs a current proportional to absolute temperature with a wide 240 °C‑1105 °C range…
The TMP17 integrates a temperature‑dependent current source that provides a nominal output of 1 µA per kelvin (1 µA/K). It operates from a single supply (1.4 V‑13 V typical) and is supplied in a low‑cost SO‑8 surface‑mount package. Its high output impedance makes it immune to voltage noise and lead resistance, while its wide operating temperature range makes it suitable for appliance, automotive, HVAC and industrial temperature sensing.
The device includes built‑in laser‑trimmed resistors for accurate scale factor, and can be calibrated with a single temperature trim to improve accuracy. Detailed specifications cover accuracy, non‑linearity, supply‑rejection, thermal characteristics, and absolute maximum ratings. Application circuits illustrate voltage‑output conversion, differential measurements, and thermostat implementations.
| Operating Temperature Range | 240 °C to 1105 °C |
|---|---|
| Scale Factor | 1 µA/°C |
| Maximum Supply Voltage | 130 V |
| Maximum Forward Voltage | 144 V |
