Description and Introduction

Serial Digital Output Thermometers The TMP04FS is a temperature sensor manufactured by Analog Devices (AD). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Temperature Range:** -25°C to +100°C  
- **Accuracy:** ±1.5°C (typical)  
- **Output Type:** Digital (Pulse Width Modulated)  
- **Supply Voltage:** 4.5V to 7V  
- **Current Consumption:** 600µA (typical)  
- **Output Frequency:** 35Hz (typical)  
- **Package:** 8-Lead SOIC (FS suffix)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The TMP04FS is a monolithic temperature sensor that converts temperature into a digital PWM signal.  
- It provides a linear output with a duty cycle proportional to the measured temperature.  
- No external calibration or trimming is required.  

### **Features:**  
- **Digital PWM Output:** Eliminates the need for A/D conversion.  
- **Wide Supply Range:** Operates from 4.5V to 7V.  
- **Low Power Consumption:** Typically 600µA.  
- **High Accuracy:** ±1.5°C over the operating range.  
- **Single-Supply Operation:** No negative voltage required.  
- **Compact Package:** 8-Lead SOIC for space-constrained applications.  

The TMP04FS is designed for applications requiring accurate temperature sensing with a simple digital interface.
