Description and Introduction

Digital temperature sensor and thermal watchdog The LM75AD is a digital temperature sensor and thermal watchdog manufactured by Philips (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage:** 2.8V to 5.5V  
- **Temperature Range:** -55°C to +125°C  
- **Accuracy:** ±2°C (from -25°C to +100°C)  
- **Resolution:** 0.125°C (9 to 12-bit selectable)  
- **Interface:** I²C-bus compatible (up to 400 kHz)  
- **Power Consumption:**  
  - Operating: 500 µA (typical)  
  - Shutdown: 3.5 µA (typical)  
- **Package:** SO-8  

### **Descriptions:**
- The LM75AD is a digital temperature sensor with an I²C interface, designed for system thermal management.  
- It includes a delta-sigma analog-to-digital converter (ADC) for temperature measurement.  
- The sensor can function as a standalone thermostat with programmable hysteresis and overtemperature shutdown.  
- It features an open-drain output (OS) that activates when the temperature exceeds a user-defined threshold.  

### **Features:**
- **Digital Output:** Provides temperature readings via I²C.  
- **Programmable Hysteresis:** Prevents rapid toggling of the OS output near the threshold.  
- **Thermal Watchdog:** OS output can trigger system shutdown if temperature exceeds limits.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Small Form Factor:** SO-8 package for space-constrained designs.  

This information is based solely on the manufacturer's datasheet and technical documentation.
