Device Overview
Texas Instruments LM50BIM3X/NOPB is an exact-order temperature sensor supplied in SOT-23-3. Selection of this exact part is driven primarily by 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 | LM50B | 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
For supply range, 4.5 V to 10 V is the approved value. Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. Sensor Type is temperature sensor. Defines the measured physical quantity and sensing architecture that a compatible substitute must preserve. At LM50B: +/-2 degC max at 25 degC; +/-3 degC max over temperature, the accuracy grade 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.
When selecting the SOT-23 LM50 accuracy grade, compare this LM50BIM3X/NOPB with LM50CIM3X/NOPB. TI specifies an LM50B maximum temperature error of ±3°C over its applicable range, versus ±4°C for LM50C. The LM50BIM3X/NOPB specified temperature range also depends on legacy versus newer chip revision, so confirm the exact device revision and operating range before procurement.
