Device Overview
Designed as a temperature sensor, Texas Instruments LM50CIM3X/NOPB uses the SOT-23-3 package. For substitution or design review, the strongest comparison points are Supply range (4.5 V to 10 V), Package / packing (SOT-23-3, large tape and reel), Sensor Type (temperature sensor).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Supply range | 4.5 V to 10 V | Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. |
| Package / packing | SOT-23-3, large tape and reel | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Sensor Type | temperature sensor | Defines the measured physical quantity and sensing architecture that a compatible substitute must preserve. |
| Accuracy Grade | LM50C | Defines the sensor error budget for this exact B/C grade; the tighter B grade reduces worst-case temperature-measurement uncertainty relative to the C grade. |
Sensor Selection Notes
Supply range is 4.5 V to 10 V. Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. For sensor type, temperature sensor is the approved value. Defines the measured physical quantity and sensing architecture that a compatible substitute must preserve. Accuracy Grade is LM50C: +/-3 degC max at 25 degC; +/-4 degC max over temperature. Defines the sensor error budget for this exact B/C grade; the tighter B grade reduces worst-case temperature-measurement uncertainty relative to the C grade. Technical condition: TI LM50 grade specifications.
The package / packing is SOT-23-3, large tape and reel; this determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
For tighter LM50 temperature-accuracy requirements, compare this LM50CIM3X/NOPB (±4°C maximum over its specified temperature range) with LM50BIM3X/NOPB (LM50B grade: ±3°C maximum over its applicable range). TI lists separate legacy and newer chip temperature limits for the BIM3X/NOPB order code; review the revision and accuracy conditions before selecting a different grade.
