Overview
The LM75BDP,118 is a digital temperature sensor and thermal watchdog produced by NXP USA Inc. This device utilizes an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique to provide accurate temperature measurements. It is designed for a wide range of applications requiring precise temperature monitoring and control.
The LM75BDP,118 is a pin-for-pin replacement for industry-standard LM75 and LM75A models, offering improved temperature resolution and specifications over a power supply range from 2.8 V to 5.5 V. It features an I2C-bus interface, allowing up to eight devices to be connected on the same bus without address conflicts.
