Description and Introduction

Remote and Local Temperature Sensor with N-Factor and Series-R Correction in MSOP-8 8-SOIC -40 to 125 The TMP411AD is a temperature sensor manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Temperature Range:**  
  - Local Sensor: -40°C to +125°C  
  - Remote Sensor: -55°C to +150°C  
- **Accuracy:**  
  - Local Sensor: ±1°C (max) from +60°C to +100°C  
  - Remote Sensor: ±1°C (max) from +60°C to +100°C (diode-connected 2N3904)  
- **Resolution:** 0.0625°C  
- **Supply Voltage:** 2.7V to 5.5V  
- **Interface:** I²C/SMBus-compatible  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The TMP411AD is a high-precision digital temperature sensor with a built-in local temperature sensor and remote temperature sensing capability. It monitors the temperature of a remote diode-connected transistor (e.g., CPU diode) and its own die temperature. It is designed for applications requiring accurate thermal management, such as servers, industrial systems, and consumer electronics.  

### **Features:**  
- **Dual Temperature Monitoring:** Measures local and remote temperatures.  
- **Programmable Alert Function:** Supports overtemperature alarms.  
- **Beta Compensation:** Corrects for variations in transistor characteristics.  
- **Low Power Consumption:** Typically 45µA (active mode).  
- **Series Resistance Cancellation:** Compensates for PCB trace resistance in remote sensing.  
- **SMBus Alert Function:** Supports system interrupts for temperature events.  

For detailed electrical characteristics and application information, refer to the official Texas Instruments datasheet.

Application Scenarios & Design Considerations

Remote and Local Temperature Sensor with N-Factor and Series-R Correction in MSOP-8 8-SOIC -40 to 125

Alternative Part Number

  • LM89CIMM --: Remote/local temperature sensor with similar SMBus interface and accuracy, pin-compatible in many designs and from the same manufacturer family.
  • ADT7461ARZ --: Remote diode temperature sensor with I2C/SMBus interface and comparable accuracy, widely used as a functional substitute.
  • MAX6642ATT90 --: High-accuracy remote/local temperature sensor with SMBus interface, suitable alternative when layout and address options allow.
  • MAX6642ATT96 --: High-accuracy remote/local temperature sensor with I2C interface and small package, functionally similar alternative from a different vendor.
