Product details

Analog local temperature sensor — 8.2 mV/°C, SC-70-5

The LMT85DCKR is a Texas Instruments analog local temperature sensor that outputs a voltage linearly proportional to temperature at 8.2 mV/°C, covering a -50°C to +150°C sensing range. Accuracy is ±2.7°C across the full -50°C to 150°C range, tested from 20°C to 150°C — sufficient for general-purpose thermal monitoring and system protection in industrial and consumer boards.

Supply voltage and output characteristics

Output type is analog voltage — the ADC on the host MCU or monitor IC reads the voltage and converts to temperature using the 8.2 mV/°C slope; no digital interface or clock needed.

Package and board integration

Housed in a 5-lead SC-70-5 (SOT-353) package, 2.0 mm × 2.1 mm body, 0.65 mm pitch — a small footprint for space-constrained PCBs, with surface-mount assembly standard for reflow soldering. Available in Tape & Reel (TR) and Cut Tape (CT) for volume production or prototype quantities; the SC-70-5 is a common package compatible with standard pick-and-place equipment.

RoHS3 compliant (2011/65/EU + 2015/863), meeting the latest EU restriction directive for lead and other hazardous substances.

Frequently asked questions

What is the output scaling of the LMT85DCKR?

The output is an analog voltage with a slope of 8.2 mV/°C. At 25°C the typical output voltage is approximately 0.708 V (calculated from the slope and 0°C offset). The ADC on the host MCU reads this voltage and converts it to temperature.

What supply voltage range does the LMT85DCKR accept?

It operates from 1.8V to 5.5V, covering common logic rails. The output voltage is ratiometric to the supply, so the ADC reference should match the sensor supply for best accuracy.

What package does the LMT85DCKR come in?

It is supplied in a 5-lead SC-70-5 (SOT-353) surface-mount package, 2.0 mm × 2.1 mm body, 0.65 mm pitch.
