- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The **MAX633ACPA** is a precision **3.3V** voltage reference with low drift and high stability.  
- It provides a stable output voltage with minimal variations due to input voltage or load changes.  
- Suitable for applications requiring accurate voltage references, such as data converters, power supplies, and measurement systems.  

### **Features:**  
- **Low Power Consumption:** 400µA typical operating current.  
- **High Accuracy:** ±0.5% initial voltage tolerance.  
- **Low Drift:** 50ppm/°C temperature coefficient ensures stability over temperature.  
- **Stable Output:** Excellent line and load regulation.  
- **Wide Supply Range:** Operates from **4V to 12V** input voltage.  
- **No External Components Required:** Internal trimming eliminates the need for external adjustments.  
- **8-Pin PDIP Package:** Easy-to-use through-hole mounting option.  

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

Application Scenarios & Design Considerations

CMOS fixed +15V output voltage, adjustable output with 2 resistors step-up switching regulator. 5% output accuracy.

Alternative Part Number

  • LTC1052CN8 --: Precision chopper-stabilized op-amp in 8-pin DIP with very low offset voltage, functionally similar to the MAX633 and pin-compatible in most circuits.
  • ICL7650CPA --: Chopper-stabilized operational amplifier in 8-pin DIP offering ultra-low offset and drift, a common drop-in style replacement for MAX63x chopper op-amps.
  • TLC2652ACP --: Low-offset chopper-stabilized CMOS op-amp in 8-pin DIP, suitable alternative when the MAX633 is unavailable, with comparable precision characteristics.
