- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The MAX635AEPA is a high-precision, low-drift voltage reference designed for applications requiring stable and accurate voltage references. It provides a fixed 5V output with excellent temperature stability and low noise performance.  

### **Features:**  
- **Low Drift:** 10ppm/°C temperature coefficient ensures stability over temperature variations.  
- **High Accuracy:** ±0.5% initial accuracy.  
- **Low Noise:** 4µVp-p noise for precision applications.  
- **Low Power Consumption:** 1.2mA typical operating current.  
- **Wide Operating Temperature Range:** -40°C to +85°C.  
- **Stable Over Time:** 30ppm/1000hrs long-term stability.  
- **No External Components Required:** Simple to use with minimal external circuitry.  

This information is strictly factual and based on the manufacturer's datasheet.
