Frequently Asked Questions
What is the temperature measurement accuracy and resolution of the LM75AIMX/NOPB?
The LM75AIMX/NOPB offers ±2°C accuracy over the -25°C to +100°C range and ±3°C over the full -55°C to +125°C range. It provides 9-bit digital resolution, equivalent to 0.5°C per LSB, making it suitable for precise thermal monitoring applications.
What interface does the LM75AIMX/NOPB use and how many devices can share the same bus?
The LM75AIMX/NOPB uses a 2-wire I2C/SMBus serial interface operating up to 400 kHz. It includes 3 configurable address pins (A0, A1, A2), allowing up to 8 LM75A devices to coexist on a single bus without address conflicts.
What is the OS (overtemperature shutdown) output and how is it configured?
The OS pin is an open-drain output that goes active when the measured temperature exceeds a user-programmable TOS threshold register (default 80°C). It reactivates when temperature drops below the THYST threshold (default 75°C), providing a 5°C hysteresis. It can be set to comparator or interrupt mode via the configuration register.
What package and supply voltage does the LM75AIMX/NOPB use?
The LM75AIMX/NOPB comes in an 8-pin SOIC (Small Outline IC) surface-mount package with a body of 4.9mm × 3.9mm. It operates from a single supply voltage of 2.7V to 5.5V, drawing a typical supply current of only 1mA, making it suitable for power-sensitive designs.
What are the main applications for the LM75AIMX/NOPB?
The LM75AIMX/NOPB is commonly used in system thermal management for servers, desktops, and laptops, as well as industrial process control, HVAC systems, battery chargers, and telecom equipment. Its I2C interface and low power consumption make it ideal for distributed temperature monitoring in embedded and IoT systems.
