LMT86 Analog Temperature Sensor

@@ -0,0 +1,51 @@+# LMT86++**Texas Instruments** · Temperature Sensor · SC70-5++The LMT86 is a precision analog temperature sensor with a near-linear negative-slope voltage output (about -10.9 mV/C). It is factory-trimmed for +-0.4 C typical accuracy, draws little current, and needs no external calibration, feeding an MCU ADC directly for thermal monitoring in a tiny SC70-5.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Power supply ground. Direct connection to the back side of the die; tie to system ground. |+| 2 | GND | power_in | Power supply ground. Direct connection to the back side of the die; tie to system ground (same net as pin 1). |+| 3 | OUT | output | Analog output voltage inversely proportional to temperature (average sensor gain −10.9 mV/°C). Push-pull, ±50 µA drive, short-circuit protected, can drive up to 1100 pF load. |+| 4 | VDD | power_in | Positive supply voltage, 2.2 V to 5.5 V. Bypass with a ceramic capacitor (typ. 0.1 µF) close to the pin. Tied internally to pin 5. |+| 5 | VDD | power_in | Positive supply voltage, 2.2 V to 5.5 V (same net as pin 4). Both VDD pins should be tied together and bypassed. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Analog (voltage-output) temperature sensor |+| Output slope | -10.9 mV/C (near-linear) |+| Accuracy | +-0.4 C typ |+| Range | -50 C to 150 C |+| Supply voltage | 2.2 V to 5.5 V |+| Supply current | 5.4 uA typ |+| Operating temperature | -50 C to 150 C |++## Ordering variants++- `LMT86DCK`+- `LMT86DCK-Q1`+- `LMT86LP`+- `LMT86LPM`+- `LMT86LPG`++## CAD (KiCad official)++- Symbol: `lmt86.kicad_sym`+- Footprint: `lmt86.kicad_mod`+- 3D model: SC70-5 body from KiCad `Package_TO_SOT_SMD/SOT-353_SC-70-5`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lmt86.pdf) (30 pp, sha256 `541641c8448be4c3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
