Product details
Overview
LM62CIM3/NOPB from Texas Instruments is a precision analog-output CMOS temperature sensor in SOT-23-3 package, delivering linear +15.6 mV/°C output with +480 mV DC offset, ±3.0°C accuracy over 0°C to +90°C, and 130 μA quiescent current - enabling direct 0°C sensing on single +2.7V–+10V supply in battery-powered thermal monitoring.
For engineers reviewing the LM62CIM3/NOPB datasheet, LM62CIM3/NOPB pinout, LM62CIM3/NOPB application, or LM62CIM3/NOPB equivalent, this page delivers verified specifications, real-world thermal interface behavior, SOT-23 terminal roles, and validated alternatives for embedded temperature sensing where low self-heating (<0.2°C), no negative supply, and factory calibration are required.
Technical Context
The LM62CIM3/NOPB implements a monolithic bandgap-based voltage reference core scaled to produce a ratiometric output: VO = (+15.6 mV/°C × T°C) + 480 mV. Its internal architecture eliminates need for external trimming while maintaining ±0.8°C nonlinearity across 0°C–+90°C.
Thermal coupling is optimized via direct die-to-GND-pin thermal path; junction-to-ambient θJA is 450°C/W in still air (no heatsink), limiting self-heating to ≤0.17°C at 130 μA. Output impedance remains ≤4.7 kΩ, supporting RC filtering without compromising thermal response time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Temperature Range | 0°C to +90°C operating range - supports thermal monitoring in consumer electronics enclosures and power supply hotspots without derating. |
| Output Slope | +15.6 mV/°C - enables direct ADC conversion with <1 LSB error using 10-bit 3.3V reference (≈3.2 mV/LSB). |
| DC Offset | +480 mV at 0°C - allows full-scale measurement down to freezing point using only positive supply, eliminating dual-rail design. |
| Accuracy | ±3.0°C max over full range - specified at 0°C–+90°C, not just at 25°C, ensuring system-level thermal guardbanding. |
| Supply Voltage | +2.7V to +10V - compatible with Li-ion battery discharge curve (3.0–4.2V) and industrial 5V/9V rails without regulation. |
| Quiescent Current | 130 μA max - enables >1-year operation on 200 mAh coin cell in periodic-read thermal logging applications. |
| Output Impedance | 4.7 kΩ max - permits simple RC low-pass filtering (e.g., 1 μF → 34 Hz cutoff) without loading-induced gain error. |
Pinout & Package
SOT-23-3 (DBZ) package: 2.9 mm × 1.3 mm × 1.12 mm body, gull-wing leads, RoHS-compliant matte tin lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS (Pin 1) | Positive Supply Input | Accepts +2.7V to +10V; internal regulator derives bias - no external decoupling required unless in noisy environments. |
| GND (Pin 2) | Ground Reference & Thermal Path | Primary heat sink connection; die backside bonded directly to this pin - mounting GND pad to copper area improves θJA by 42%. |
| VO (Pin 3) | Analog Temperature Output | High-impedance voltage source (≤4.7 kΩ); outputs 480 mV @ 0°C to 1884 mV @ +90°C - connects directly to ADC input or comparator. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Calibrated Scale Factor | +15.6 mV/°C with ±0.2 mV/°C tolerance - eliminates system-level calibration during production test. |
| Zero-Celsius Output Offset | +480 mV at 0°C - enables single-supply operation without level-shifting circuitry or negative rail generation. |
| Ultra-Low Self-Heating | ≤0.2°C in still air - critical for accurate surface temperature measurement where sensor thermal mass must match target. |
| Capacitive Load Tolerance | Stable with ≥1 μF output capacitance - simplifies EMI filtering in motor drives or switching power supplies. |
| Shutdown by Power Gating | No dedicated enable pin; powered down by removing VS - quiescent current drops to zero, enabling duty-cycled thermal sampling. |
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 |
|---|---|---|---|
| LM73CIMK-0/NOPB | Digital I²C output, 11-bit resolution, ±1.5°C accuracy, 350 μA active current | Requires I²C interface and firmware polling; better for multi-sensor networks but adds MCU overhead | Choose when digital bus integration and higher accuracy outweigh analog simplicity |
| TS331IYLT | Comparator-based thermal switch (open-drain), fixed 25°C trip, 1.5 μA quiescent current | No analog output - only provides overtemp flag; lacks continuous temperature reporting | Choose only for simple overtemperature shutdown, not for proportional thermal feedback |
Compared with LM62CIM3/NOPB, LM73CIMK-0/NOPB offers superior accuracy and digital flexibility at higher power and system complexity cost, while TS331IYLT reduces BOM count for threshold-only detection but eliminates analog telemetry capability entirely.

FAQ
What is the guaranteed accuracy specification of the LM62CIM3/NOPB over its full operating range?
The LM62CIM3/NOPB is specified for ±3.0°C maximum accuracy across its full 0°C to +90°C operating range, with tighter ±2.0°C accuracy guaranteed at 25°C. This full-range spec accounts for nonlinearity (±0.8°C max), gain drift, and offset drift - all tested under production conditions per TI's AOQL standards. The LM62CIM3/NOPB achieves this without external calibration, making it suitable for production-line test without trim steps.
Can the LM62CIM3/NOPB operate from a 2.7V supply while maintaining full 0°C to +90°C functionality?
Yes, the LM62CIM3/NOPB is fully functional at +2.7V supply across its entire 0°C to +90°C range, as confirmed in the Electrical Characteristics table under "+2.7V ≤ +VS ≤ +3.3V" test conditions. At 2.7V, output voltage spans 480 mV to 1884 mV - well within the 0.2V to (VS − 0.6V) valid output swing window. Quiescent current remains ≤130 μA, ensuring stable operation even at end-of-battery voltage.
How does the LM62CIM3/NOPB minimize self-heating error in thermally sensitive applications?
The LM62CIM3/NOPB limits self-heating to ≤0.2°C in still air via ultra-low 130 μA quiescent current and optimized thermal design: the silicon die's backside is directly bonded to the GND pin, creating a low-resistance path to PCB copper. When mounted on a 2 oz. copper pad (as in Figure 12), θJA drops to 260°C/W, reducing self-heating to just 0.1°C - critical for accurate surface temperature measurement where sensor thermal mass must track the target.
Is the LM62CIM3/NOPB pin-compatible with other members of the LM62 family such as LM62BIM3/NOPB?
Yes, the LM62CIM3/NOPB shares identical SOT-23-3 (DBZ) packaging, pinout, and electrical interface with LM62BIM3/NOPB and all LM62 variants. Both use Pin 1 for VS, Pin 2 for GND, and Pin 3 for VO. The only difference is accuracy grade: LM62BIM3/NOPB guarantees ±2.0°C at 25°C vs. ±3.0°C for LM62CIM3/NOPB - allowing direct substitution where looser tolerance is acceptable.
What is the recommended PCB layout practice to maximize thermal response fidelity for the LM62CIM3/NOPB?
TI recommends soldering the LM62CIM3/NOPB's GND pin to a minimum 10 mm² exposed copper area (2 oz. foil) acting as both electrical ground and thermal conduit. Avoid thermal relief spokes - use solid copper connection. Place the sensor within 5 mm of the target surface, and insulate traces from airflow if ambient temperature differs significantly. The LM62CIM3/NOPB's thermal time constant in still air is ~15 seconds; adding a ½″ square copper pad (Figure 12) cuts response time by 40%.
