Description and Introduction

High Common-Mode Voltage DIFFERENCE AMPLIFIER The INA117P is a high common-mode voltage difference amplifier manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Common-Mode Voltage Range:** ±200V  
- **Supply Voltage Range:** ±4.5V to ±18V  
- **Input Offset Voltage:** 500μV (max)  
- **Input Bias Current:** 10μA (max)  
- **Gain Accuracy:** 0.01% (typ)  
- **Bandwidth:** 500kHz (typ)  
- **CMRR:** 86dB (min)  
- **Package:** 8-pin PDIP (Plastic DIP)  

### **Description:**  
The INA117P is designed to accurately measure small differential voltages in the presence of high common-mode voltages (up to ±200V). It provides a fixed gain of 1 and is commonly used in industrial, medical, and test equipment applications.  

### **Features:**  
- High common-mode voltage rejection  
- Wide supply voltage range  
- High accuracy and stability  
- Low input offset voltage and bias current  
- Internal precision resistors for gain stability  
- Short-circuit protection  

This amplifier is suitable for applications requiring precise measurements in high-voltage environments.

Application Scenarios & Design Considerations

High Common-Mode Voltage DIFFERENCE AMPLIFIER

Alternative Part Number

  • AD629ANZ --: High common-mode voltage difference amplifier with similar function and pin-compatible DIP-8 package, widely used as a drop-in alternative.
  • AD629BNZ --: Same AD629 series with improved grade and lower offset, suitable when tighter accuracy is needed in the same DIP-8 footprint.
  • INA149AID --: TI difference amplifier with high common-mode voltage range and similar gain configuration, though in SOIC package requiring an adapter.
