Description and Introduction

Precision INSTRUMENTATION AMPLIFIER The INA114AP is a precision instrumentation amplifier manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Supply Voltage Range:** ±2.25V to ±18V  
- **Quiescent Current:** 3 mA (max)  
- **Input Offset Voltage:** 50 µV (max)  
- **Input Offset Voltage Drift:** 0.25 µV/°C (max)  
- **Input Bias Current:** 2 nA (max)  
- **Common-Mode Rejection Ratio (CMRR):** 115 dB (min) at G = 1000  
- **Gain Range:** 1 to 10,000 (set by external resistor)  
- **Bandwidth:** 1 MHz (G = 1)  
- **Slew Rate:** 4 V/µs  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The INA114AP is a high-precision instrumentation amplifier designed for applications requiring high accuracy and stability. It features low offset voltage, low drift, and high CMRR, making it suitable for signal conditioning in medical, industrial, and test equipment.  

### **Features:**  
- **Low Offset Voltage:** Ensures accurate signal amplification.  
- **High CMRR:** Rejects common-mode noise effectively.  
- **Wide Supply Range:** Operates from ±2.25V to ±18V.  
- **External Gain Setting:** Adjustable gain via a single resistor.  
- **Low Noise:** Suitable for sensitive measurements.  
- **Stable Operation:** Minimal drift over temperature.
