Product Overview
The LMT85 is a Texas Instruments precision CMOS analog temperature sensor. Its output is a linear analog voltage inversely proportional to temperature, allowing temperature information to be represented directly as a voltage signal. The device is specified for operation from -50 to 150 °C with a recommended supply voltage range of 1.8 to 5.5 V.
Electrical characteristics include an average sensor gain of -8.2 mV/°C, typical quiescent current of 5.4 µA, and supply current of 5.4 µA typical with maximum values of 8.1 µA or 9 µA depending on the temperature condition. Power-on time is specified as 0.7 ms typical and 1.9 ms maximum with load capacitance from 0 pF to 1100 pF.
Package options include SOT/SC70 5-pin, TO-92 3-pin, and TO-92S 3-pin formats. The output supports -50 to +50 µA drive at 25 °C, with specified load regulation, line regulation, ESD ratings, and absolute maximum limits for supply voltage, output voltage, output current, input current, junction temperature, and storage temperature.

Procurement Notes
When requesting a quote for LMT85, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What type of sensor is the LMT85?
The LMT85 is a Texas Instruments precision CMOS analog temperature sensor. Its output is a linear analog voltage that is inversely proportional to temperature, so the measured temperature is represented through the output voltage behavior.
What supply voltage range does the LMT85 support?
The recommended operating supply voltage range for the LMT85 is 1.8 to 5.5 V. Absolute maximum supply voltage is specified separately as -0.3 to 6 V and should not be treated as the normal operating range.
