- **Input Common-Mode Voltage Range:** ±10V (with ±15V supply)  
- **Gain:** Fixed at 1 (unity gain)  
- **Bandwidth:** 1MHz (typical)  
- **Slew Rate:** 4V/µs (typical)  
- **Input Offset Voltage:** 250µV (max)  
- **Input Bias Current:** 500nA (max)  
- **CMRR (Common-Mode Rejection Ratio):** 86dB (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SOIC-8, PDIP-8  

### **Descriptions:**  
The INA133 is a high-precision unity-gain difference amplifier designed for applications requiring accurate differential signal amplification. It is optimized for low distortion and high common-mode rejection, making it suitable for instrumentation, industrial control, and audio processing.  

### **Features:**  
- **High Common-Mode Rejection:** Minimizes errors in noisy environments.  
- **Wide Supply Range:** Supports dual-supply operation.  
- **Low Offset Voltage and Drift:** Ensures accuracy over temperature.  
- **Unity-Gain Stable:** No external components needed for gain setting.  
- **Robust Input Protection:** Handles up to ±40V without damage.
