### **Descriptions:**  
The INA163UA is a low-noise, low-distortion instrumentation amplifier designed for precision signal conditioning. It provides high common-mode rejection and low input offset voltage, making it suitable for applications requiring accurate amplification of small differential signals in noisy environments.  

### **Features:**  
- **Low Noise:** 1 nV/√Hz at 1 kHz  
- **Low Distortion:** 0.001% THD at 1 kHz  
- **Wide Supply Range:** ±2.25V to ±18V  
- **High CMRR:** 100 dB (min)  
- **Low Input Offset Voltage:** 50 µV (max)  
- **Low Input Bias Current:** 5 nA (max)  
- **Internal Gain Set Resistors:** Eliminates external resistors for fixed gains  
- **Wide Bandwidth:** 1 MHz (G = 100)  

This amplifier is commonly used in medical instrumentation, audio processing, and industrial measurement systems.

Application Scenarios & Design Considerations

Low-Noise/ Low-Distortion INSTRUMENTATION AMPLIFIER

Alternative Part Number

  • AD8429ARZ --: Low-noise instrumentation amplifier with similar gain range and bandwidth, pin-compatible in many designs and a common drop-in substitute for the INA163.
  • LT1167CS8 --: Precision instrumentation amplifier offering comparable low noise and gain performance, suitable replacement in sensor signal conditioning circuits.
  • AD620ANZ --: Classic low-cost instrumentation amplifier with similar architecture and gain setting via single resistor, widely used as an alternative when slightly lower bandwidth is acceptable.
