Description and Introduction

Remote and Local Temperature Sensor with N-Factor and Series-R Correction in MSOP-8 8-SOIC -40 to 125 The TMP411BDR is a temperature sensor manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI) / Burr-Brown (BB)  
- **Package:** SOIC-8  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Temperature Measurement Range:** -40°C to +125°C (Local), -40°C to +127°C (Remote)  
- **Accuracy:**  
  - ±1°C (Local, 0°C to +70°C)  
  - ±2°C (Remote, 0°C to +70°C)  
- **Resolution:** 0.0625°C (12-bit)  
- **Interface:** I²C/SMBus compatible  
- **Remote Diode Sensing:** Supports 2N3904 or substrate transistors  
- **Programmable Alert Function:** Overtemperature/undertemperature alarms  
- **Power Consumption:** 50µA (Typical)  

### **Descriptions:**  
The TMP411BDR is a high-precision digital temperature sensor with local and remote sensing capabilities. It integrates a local temperature sensor and can also monitor the temperature of an external diode-connected transistor (e.g., CPU diode). It communicates via I²C/SMBus and provides programmable alerts for temperature thresholds.  

### **Features:**  
- Local and remote temperature sensing  
- Programmable temperature limits with alert function  
- Low power consumption  
- I²C/SMBus interface with up to 400kHz operation  
- Supports multiple remote sensor configurations  
- Small SOIC-8 package for space-constrained applications  

This information is sourced from TI's official datasheet for the TMP411BDR.
