Description and Introduction

Fast-Settling FET-Input INSTRUMENTATION AMPLIFIER The INA110SG is a precision instrumentation amplifier manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** ±4.5V to ±18V  
- **Quiescent Current:** 3.5mA (typical)  
- **Gain Range:** 1 to 500 (set via external resistor)  
- **Input Offset Voltage:** 50µV (max)  
- **Input Bias Current:** 5nA (max)  
- **Common-Mode Rejection Ratio (CMRR):** 106dB (min)  
- **Bandwidth:** 1MHz (G = 100)  
- **Slew Rate:** 3V/µs  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SOIC (SG suffix)  

### **Descriptions:**  
The INA110SG is a high-speed, precision instrumentation amplifier designed for applications requiring low noise, high accuracy, and fast signal processing. It features laser-trimmed input circuitry for low offset voltage and drift, making it suitable for medical instrumentation, data acquisition, and industrial control systems.  

### **Features:**  
- **High CMRR:** Ensures excellent noise rejection in noisy environments.  
- **Low Noise:** 10nV/√Hz at 1kHz (G = 100).  
- **Wide Gain Range:** Adjustable from 1 to 500 with a single external resistor.  
- **Fast Settling Time:** 4µs to 0.01% (G = 100).  
- **High Input Impedance:** 10¹⁰Ω (typical).  
- **Overvoltage Protection:** Up to ±40V on inputs.  
- **Laser-Trimmed Resistors:** Ensures high accuracy and stability.  

The INA110SG is ideal for applications requiring precision signal amplification with high speed and low distortion.

Application Scenarios & Design Considerations

Fast-Settling FET-Input INSTRUMENTATION AMPLIFIER

Alternative Part Number

  • AD524SD --: Precision instrumentation amplifier with similar gain and bandwidth, available in the same hermetic DIP package, widely used as a direct substitute in instrumentation designs.
  • AD625SD --: Programmable-gain instrumentation amplifier offering comparable performance and pin-compatible hermetic package, suitable for high-accuracy signal conditioning.
  • AMP01 --: Low-noise instrumentation amplifier with similar gain range and supply requirements, a practical alternative when the INA110 is unavailable.
  • INA114AP --: Low-cost instrumentation amplifier with similar gain range and low offset, widely available and functionally interchangeable in most INA110 applications.
