Design a Custom BoardAbout This Component
The LM75B is a digital temperature sensor with I2C interface providing 11-bit temperature measurement with 0.125°C resolution over -55°C to +125°C range. It features a programmable overtemperature shutdown output with configurable hysteresis, operates from 2.8V to 5.5V, and supports up to 8 devices on a single I2C bus. Ideal for thermal monitoring, thermostat applications, and precise temperature measurement in industrial and consumer electronics.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
