Texas Instruments LM60BIZ/NOPB

Overview

LM60BIZ/NOPB from Texas Instruments is a precision analog bipolar temperature sensor in TO-92 (straight leads) package, delivering linear 6.25 mV/°C output with 424 mV offset, ±3°C accuracy over −40°C to +125°C (new chip), 2.7V–10V supply range, and 70 μA max quiescent current - used for battery management and thermal monitoring in compact consumer electronics.

For engineers reviewing the LM60BIZ/NOPB datasheet, LM60BIZ/NOPB pinout, LM60BIZ/NOPB application, or LM60BIZ/NOPB equivalent, this page delivers verified technical context, real-world design meaning of specifications, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and application-level differences.

Technical Context

The LM60BIZ/NOPB implements a Class-A emitter-follower output stage, enabling low-output-impedance sourcing (≤800 Ω) while sinking <1 μA - critical for minimizing loading-induced temperature error. Its transfer function VO = (6.25 mV/°C × T °C) + 424 mV is factory-calibrated and applies across the full −40°C to +125°C range for new-chip variants.

Thermal self-heating is limited to ≤0.1°C in still air due to 70 μA max quiescent current and TO-92 package's 135.9°C/W junction-to-ambient thermal resistance (new chip). No shutdown control pin exists; power gating is achieved by driving +VS directly from logic outputs.

Key Specifications

Pinout & Package

FAQ

What is the guaranteed accuracy specification for LM60BIZ/NOPB across its full operating temperature range?

The LM60BIZ/NOPB is specified for ±3°C accuracy over −40°C to +125°C when using the new-chip variant (date code indicating RFB die). Legacy-chip units (GF6/SHE die) maintain ±3°C accuracy only from −25°C to +125°C, though they operate safely down to −40°C. Both variants share identical LM60BIZ/NOPB part marking and TO-92 packaging.

Can LM60BIZ/NOPB measure temperatures below 0°C with a single positive supply?

Yes. The LM60BIZ/NOPB features a fixed 424 mV DC offset at 0°C and linear 6.25 mV/°C sensitivity, so its output voltage drops to 174 mV at −40°C - well above ground and fully compatible with 0–3.3V ADC inputs. No negative supply or level-shifting circuitry is needed to resolve sub-zero temperatures.

What is the maximum allowable capacitive load on the VOUT pin of LM60BIZ/NOPB?

The LM60BIZ/NOPB output can drive up to 1 μF capacitance without instability, forming a 199 Hz low-pass filter with its 800 Ω max output impedance. Larger capacitors increase thermal response lag; TI recommends limiting output capacitance to ≤1 μF unless slower system response is acceptable and noise immunity justifies the trade-off.

Does LM60BIZ/NOPB require an external decoupling capacitor on the +VS pin?

Yes. A 0.1 μF ceramic capacitor from +VS to GND is mandatory in electrically noisy environments to prevent supply ripple from coupling into the analog output. This capacitor must be placed as close as possible to the LM60BIZ/NOPB pins, especially when powered from switching regulators or shared digital rails.

How does the TO-92 package of LM60BIZ/NOPB affect thermal response time compared to SOT-23?

The TO-92 package (LM60BIZ/NOPB) exhibits slower thermal response than SOT-23 variants due to higher thermal mass and lower surface-area-to-volume ratio. In still air, TO-92 reaches 63% of final temperature in ~12 seconds versus ~6 seconds for SOT-23 - a key consideration for fast transient thermal event detection in LM60BIZ/NOPB implementations.
