Product details
Overview
LM60CIM3/NOPB from Texas Instruments is a precision analog bipolar temperature sensor in SOT-23-3 package, delivering linear 6.25 mV/°C output with 424 mV DC offset for −40°C to +125°C sensing range, ±4°C max accuracy over full range, and 70 μA max quiescent current - enabling battery-powered thermal monitoring in space-constrained PCB layouts.
For engineers reviewing the LM60CIM3/NOPB datasheet, LM60CIM3/NOPB pinout, LM60CIM3/NOPB application, or LM60CIM3/NOPB equivalent, this page delivers verified specifications, validated pin functions, real-world thermal use cases, and confirmed alternative options for embedded temperature sensing where single-supply operation, negative-temperature capability, and low self-heating are critical.
Technical Context
The LM60CIM3/NOPB implements a Class-A emitter-follower output stage, providing low-output-impedance analog voltage proportional to die temperature without requiring external components. Its transfer function VO = (6.25 mV/°C × T) + 424 mV is factory-calibrated and stable across 2.7V–10V supply, eliminating need for negative rails or digital compensation.
Thermal response is governed by junction-to-ambient resistance (RθJA = 240.6°C/W for new-chip SOT-23), limiting self-heating to ≤0.1°C in still air - a key enabler for surface-mount thermal measurement on PCBs, batteries, and power modules where thermal mass and airflow are uncontrolled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Temperature Range | −40°C to +125°C operating range; enables thermal monitoring in automotive under-hood, industrial motor drives, and consumer battery packs. |
| Output Sensitivity | 6.25 mV/°C with ±0.2 mV/°C variation; allows direct ADC interfacing with <1 LSB error using 12-bit converters at room temperature. |
| Offset Voltage | 424 mV at 0°C; permits accurate reading of sub-zero temperatures using only a single positive supply (e.g., 3.3V or Li-ion). |
| Accuracy | ±4°C max over full −40°C to +125°C range; specified for new-chip revision, supporting reliable thermal shutdown in safety-critical systems. |
| Quiescent Current | 70 μA max at 25°C (new chip); enables multi-year battery life in IoT sensors and portable diagnostics equipment. |
| Output Impedance | 800 Ω max; supports RC filtering (e.g., 1 μF capacitor) for noise rejection without degrading thermal response time. |
| Nonlinearity | ±0.8°C max; ensures monotonic output across full range, simplifying calibration and reducing software correction overhead. |
Pinout & Package
SOT-23-3 (DBZ) package: 2.37 mm × 2.92 mm footprint with gull-wing leads; thermally optimized for PCB-mounted sensing with GND pin directly connected to die backside for minimal thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +VS | Power input | Accepts 2.7V–10V DC; powers internal bandgap reference and output stage; no external decoupling required for most applications. |
| VOUT | Analog output | Emitter-follower voltage output; sources up to 10 mA but sinks <1 μA; connects directly to ADC input or comparator without buffering. |
| GND | Reference ground | Die substrate connection and thermal path; must be tied to system ground plane to minimize thermal gradient between die and PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from 2.7V–10V with no negative rail needed - reduces BOM count and layout complexity in portable and isolated systems. |
| Factory-calibrated linearity | ±0.8°C nonlinearity eliminates need for per-unit polynomial correction, lowering firmware development cost in high-volume production. |
| Low self-heating | 0.1°C max temperature rise in still air (SOT-23) ensures measurement fidelity when mounted directly on heat-generating components like MOSFETs or LDOs. |
| ESD robustness | ±2500 V HBM rating protects against handling damage during assembly and field service in unshielded environments. |
| Thermal mounting flexibility | Can be cemented, glued, or soldered to surfaces - die-to-GND thermal path enables accurate surface temperature tracking within ±0.1°C. |

FAQ
What is the guaranteed accuracy specification for LM60CIM3/NOPB across its full operating temperature range?
The LM60CIM3/NOPB is specified for ±4°C maximum accuracy over the full −40°C to +125°C temperature range, applicable to the new-chip revision. This accuracy includes all contributions from gain error, offset drift, and nonlinearity, and is verified per TI's production test flow. The LM60CIM3/NOPB achieves this performance without requiring external calibration or trimming circuits.
Does LM60CIM3/NOPB require external components for basic operation?
No, LM60CIM3/NOPB operates with zero external components in standard configurations. Its emitter-follower output drives ADC inputs directly, and its 2.7V–10V supply range accommodates common logic rails. A 0.1 μF bypass capacitor on +VS is recommended only in electrically noisy environments - not required for functional operation per the datasheet.
How does the 424 mV offset in LM60CIM3/NOPB enable negative-temperature measurement?
The 424 mV offset at 0°C means LM60CIM3/NOPB outputs 174 mV at −40°C and increases linearly at 6.25 mV/°C. This ensures the output remains above ground even at minimum temperature, allowing accurate sub-zero readings using only a single positive supply - eliminating need for dual-rail op-amps or level-shifting circuitry in battery-powered systems.
What is the thermal self-heating effect of LM60CIM3/NOPB in a typical SOT-23 PCB layout?
In still air on a standard PCB, LM60CIM3/NOPB exhibits ≤0.1°C self-heating due to its 70 μA max quiescent current and 240.6°C/W junction-to-ambient thermal resistance (new-chip SOT-23). This low self-heating preserves measurement accuracy when mounted directly on heat-generating components like power MOSFETs or LDO regulators.
Can LM60CIM3/NOPB be used in automotive applications?
LM60CIM3/NOPB is not AEC-Q200 qualified. For automotive applications, TI recommends the LM60QIM3X/NOPB (AEC-Q100 Grade 1 qualified, ±4°C over −40°C to +125°C). While LM60CIM3/NOPB shares identical electrical specs, it lacks automotive-grade screening, qualification testing, and PPAP documentation required for under-hood or safety-critical vehicle systems.
