Product details
Overview
LM60CIM3 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 offset for −40°C to +125°C sensing range, ±4°C max accuracy over full range, and 70 μA max quiescent current - used in battery-powered thermal monitoring for mobile devices and power supply modules.
For engineers reviewing the LM60CIM3 datasheet, LM60CIM3 pinout, LM60CIM3 application, or LM60CIM3 equivalent, this page provides verified electrical specifications, thermal performance data, real-world layout guidance, and validated alternative options for embedded temperature sensing where single-supply operation and negative-temperature capability are required.
Technical Context
The LM60CIM3 implements a Class A emitter-follower output stage, enabling low-output-impedance sourcing (≤800 Ω) while sinking <1 μA - ensuring minimal loading error in high-impedance ADC interfaces. Its transfer function VO = (6.25 mV/°C × T °C) + 424 mV is factory-calibrated and stable across 2.7 V to 10 V supply.
Thermal self-heating is limited to ≤0.1°C in still air (SOT-23), due to sub-70 μA quiescent current and optimized die-to-GND thermal path. No shutdown control pin is present; power gating is achieved by externally switching the +VS rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Temperature Range | −40°C to +125°C operating range - enables use in automotive under-hood and industrial ambient environments without external cold-junction compensation. |
| Accuracy | ±4°C maximum over full −40°C to +125°C range - specified for LM60C grade, supporting cost-sensitive thermal protection where ±3°C is not mandatory. |
| Output Sensitivity | 6.25 mV/°C with 424 mV offset - allows direct interfacing to 10-bit ADCs with ≥1.2 V reference without level-shifting or negative supply. |
| Supply Voltage | 2.7 V to 10 V - compatible with single-cell Li-ion (3.0–4.2 V), 3.3 V logic rails, and wide-input DC-DC outputs. |
| Quiescent Current | 70 μA maximum (new chip) - reduces self-heating to ≤0.1°C in SOT-23, critical for surface-mount thermal measurement fidelity. |
| Output Impedance | 800 Ω maximum - defines RC filter cutoff when adding output capacitance; supports ≤1 μF bypass without significant response lag. |
| Nonlinearity | ±0.8°C maximum - ensures error remains bounded across full range, simplifying linearization in firmware or analog signal chains. |
Pinout & Package
SOT-23-3 (DBZ) package: 2.37 mm × 2.92 mm nominal footprint, GND-connected die backside for thermal conduction to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +VS | Power input | Single positive supply input (2.7–10 V); powers internal bandgap reference and output stage - must be bypassed with 0.1 μF to GND in noisy environments. |
| VOUT | Analog output | Emitter-follower voltage output proportional to temperature; drives high-impedance loads directly; requires no external pull-up or pull-down. |
| GND | Ground reference | Device ground and thermal conduction path; connects internally to die backside - must be tied to low-impedance PCB ground plane for accurate thermal coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply negative-temp support | 424 mV offset enables −40°C measurement with only positive supply - eliminates need for dual-rail op-amps or level-shifters in portable systems. |
| Low self-heating | 70 μA max IQ limits thermal rise to ≤0.1°C in still air - preserves measurement accuracy when mounted on thermally sensitive PCB traces or small metal housings. |
| Robust capacitive drive | Stable with up to 1 μF output capacitance - permits simple RC filtering (199 Hz cutoff) to suppress EMI without oscillation or settling delay penalties. |
| ESD hardened | ±2500 V HBM rating - withstands handling and board-level ESD events common in consumer electronics assembly and field service. |
| Legacy/new chip compatibility | Same pinout, transfer function, and specs across chip revisions - ensures long-term BOM continuity despite internal process updates (CSO RFB vs GF6). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog-output temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM60BIM3X/NOPB | ±3°C max accuracy over −40°C to +125°C (new chip), same 6.25 mV/°C gain and SOT-23-3 package | Higher accuracy required for tighter thermal control loops (e.g., CPU thermal margining) | Select when ±3°C tolerance is mandated and cost premium is acceptable. |
| LM73CIMK-0/NOPB | Digital I²C output, 0.25°C resolution, 1.7 V to 5.5 V supply, SOT-23-6 package | Requires microcontroller with I²C interface; eliminates ADC resource but adds firmware overhead | Choose for systems needing higher resolution, digital bus integration, or lower total solution size with existing I²C infrastructure. |
Compared with LM60CIM3, LM60BIM3X/NOPB improves accuracy by 1°C at no package or pinout change, while LM73CIMK-0/NOPB trades analog simplicity for digital precision and communication flexibility - making LM60CIM3 optimal for cost-sensitive, ADC-equipped designs prioritizing minimal component count and ultra-low power.

FAQ
What is the guaranteed accuracy specification for LM60CIM3 over its full operating temperature range?
The LM60CIM3 is guaranteed to maintain ±4°C maximum accuracy across the full −40°C to +125°C temperature range, as confirmed in TI's SNIS119G datasheet Section 4 (Device Comparison) and Section 6.5 (Electrical Characteristics). This applies to both legacy and new chip revisions, and is distinct from the tighter ±3°C spec of the LM60B variant.
Does LM60CIM3 require an external negative supply to measure temperatures below 0°C?
No, LM60CIM3 does not require a negative supply. Its 424 mV output offset at 0°C enables direct measurement down to −40°C with only a single positive supply (2.7 V to 10 V), as defined by the transfer function VO = (6.25 mV/°C × T °C) + 424 mV - a key design feature confirmed in Section 3 (Description) and Figure 8-4 of the datasheet.
What is the maximum allowable output capacitive load for stable operation of LM60CIM3?
LM60CIM3 can drive up to 1 μF output capacitance stably, forming a 199 Hz low-pass filter with its 800 Ω max output impedance - sufficient for noise suppression in typical EMI environments without affecting thermal response, as detailed in Section 8.1.1 and Figure 8-1 of the LM60 datasheet.
How does the quiescent current of LM60CIM3 impact thermal measurement accuracy?
LM60CIM3's 70 μA maximum quiescent current limits self-heating to ≤0.1°C in still air (SOT-23 package), as verified in Section 8.5.3 and Table 8-2 - ensuring the sensed temperature closely matches the target surface or ambient condition without significant internal heating artifact.
Is LM60CIM3 pin-compatible with other LM60 variants such as LM60BIM3X/NOPB?
Yes, LM60CIM3 is fully pin-compatible with LM60BIM3X/NOPB and all other SOT-23-3 packaged LM60 variants - sharing identical DBZ footprint, pin 1 (+VS), pin 2 (VOUT), and pin 3 (GND) assignments, as shown in Figure 5-1 and Table 5-1 of the datasheet, enabling drop-in replacement where accuracy requirements permit.
