This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
MAXIM INTEGRATED MAX31825 1-Wire Temperature Sensor
Maxim Integrated’s MAX31825 1-Wire® Temperature Sensor provide accurate temperature measurements and a flexible functionality in a compact package.
The sensor provides 8-bit to 12-bit temperature measurements from -45°C to +145°C with better than ±1.75°C accuracy, and better than ±1°C from 0°C to +70°C. Temperature measurements are sent to the host using the 1-Wire interface, which requires only one data line that can also be used to parasitically power the sensor. Each sensor has a unique 64-bit serial code to allow multiple sensors on the same 1-Wire bus, and two address pins provide 64 addresses to identify the senor’s location on a board with multiple MAX31825 sensors.
The MAX31825 also offers an alarm output with user-definable settings and is housed in a 6-bump wafer-level package.
