Product Introduction

Overview

The LM75BD,112, produced by NXP USA Inc., is a digital temperature sensor and thermal watchdog. It utilizes an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique to provide accurate temperature measurements. This device is designed to monitor ambient temperature and can be configured for various operation modes, including stand-alone operation as a thermostat. It features an I2C-bus interface, allowing up to eight devices to be connected on the same bus without address conflicts.
