Description and Introduction

Triple Remote and Local Temperature Sensor with SMBus, I2C Interface and ACPI Compatible 16-SSOP -40 to 125 The LM83CIMQA/NOPB is a digital temperature sensor manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** National Semiconductor (NS)  
- **Part Number:** LM83CIMQA/NOPB  
- **Type:** Digital Temperature Sensor  
- **Operating Voltage:** 3.0V to 3.6V  
- **Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±1°C (typical) over full range  
- **Resolution:** 0.125°C (9-bit)  
- **Interface:** SMBus/I²C compatible  
- **Number of Channels:** 3 (monitors remote diode and internal temperature)  
- **Package:** 16-pin WQFN  
- **Features:** Programmable thresholds, alert functionality  

### **Descriptions:**
- The LM83CIMQA/NOPB is a precision digital temperature sensor designed to monitor the temperature of a remote diode (e.g., CPU diode) and its own internal temperature.  
- It communicates via the SMBus/I²C interface, allowing easy integration into digital systems.  
- The sensor provides high accuracy and programmable alert thresholds for temperature monitoring applications.  

### **Features:**
- Monitors three temperature zones (remote diode + internal sensor).  
- Supports SMBus Alert response for fault detection.  
- Programmable high/low temperature limits with hysteresis.  
- Low power consumption.  
- Suitable for system thermal management in computers, servers, and industrial applications.  

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