AUDIO DIFFERENTIAL LINE RECEIVERS +6dB (G = 1/2 or 2) The INA137 is a high-performance, differential line receiver manufactured by Texas Instruments (BB). Here are the key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±4.5V to ±18V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Gain:** Fixed at 1 (unity gain)  
- **Common-Mode Rejection Ratio (CMRR):** 90dB (typical)  
- **Bandwidth:** 1.5MHz (typical)  
- **Input Impedance:** 100kΩ (differential)  
- **Output Voltage Swing:** ±12V (with ±15V supply)  
- **Package Options:** SOIC-8  

### **Descriptions:**
The INA137 is designed to accurately receive balanced audio signals, converting differential inputs to a single-ended output while rejecting common-mode noise. It is commonly used in professional audio, telecommunications, and instrumentation applications.

### **Features:**
- High common-mode rejection for noise immunity  
- Unity gain differential-to-single-ended conversion  
- Wide supply voltage range for flexibility  
- Low distortion for high-fidelity audio applications  
- Robust performance in noisy environments  

The INA137 is ideal for applications requiring precise signal reception with minimal interference.
