Frequently Asked Questions
What is the temperature measurement range and accuracy of the LM75AIMME/NOPB?
The LM75AIMME/NOPB measures temperatures from -55°C to +125°C with a maximum accuracy of ±2°C over the -25°C to +100°C range. It provides 9-bit resolution, corresponding to a step size of 0.5°C, making it suitable for precise thermal management applications in servers, industrial equipment, and consumer electronics.
How many LM75AIMME/NOPB devices can be connected on the same I2C bus?
Up to eight LM75AIMME/NOPB devices can be connected on a single I2C/SMBus bus simultaneously. This is achieved through three hardware-selectable address pins (A0, A1, A2), each configurable to logic high or low, yielding eight unique 7-bit I2C addresses. This makes multi-zone temperature monitoring straightforward without additional bus multiplexers.
What package does the LM75AIMME/NOPB come in and what are its dimensions?
The LM75AIMME/NOPB is available in an 8-pin MSOP (Mini Small Outline Package) with a body measuring 3mm × 3mm and a height of 1.1mm. It is a surface-mount package, making it suitable for high-density PCB layouts in compact devices such as wearables, IoT nodes, and portable industrial instruments.
What is the supply voltage range and current consumption of the LM75AIMME/NOPB?
The LM75AIMME/NOPB operates from a supply voltage of 2.7V to 5.5V, covering both 3.3V and 5V logic systems. Maximum operating current is 0.5mA, and it features a shutdown mode that reduces consumption to just 3.0µA, extending battery life in energy-sensitive designs such as portable sensors and battery-backed monitoring systems.
What is a suitable replacement or alternative for the LM75AIMME/NOPB?
Common alternatives to the LM75AIMME/NOPB include the Texas Instruments TMP75 and TMP275 (12-bit resolution, pin-compatible), the Microchip MCP9800 (12-bit, I2C, same footprint), and the NXP LM75B. The TMP275 is particularly recommended for designs requiring higher accuracy (±0.5°C) while maintaining I2C/SMBus compatibility and a similar package outline.
