Description and Introduction

Quad Over-The-Top Micropower Rail-to-Rail Input and Output Op Amps The LT1491AIN is a dual operational amplifier (op-amp) manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±1.25V to ±15V (Dual Supply), 2.5V to 30V (Single Supply)  
- **Input Offset Voltage:** 300µV (Typical), 1.5mV (Maximum)  
- **Input Bias Current:** 25nA (Typical), 100nA (Maximum)  
- **Input Offset Current:** 5nA (Typical), 50nA (Maximum)  
- **Gain Bandwidth Product:** 1MHz (Typical)  
- **Slew Rate:** 0.4V/µs (Typical)  
- **Common Mode Rejection Ratio (CMRR):** 90dB (Typical)  
- **Supply Current per Amplifier:** 500µA (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin PDIP  

### **Descriptions:**
- The LT1491AIN is a dual precision op-amp with low power consumption and rail-to-rail output swing.  
- It is designed for battery-powered and precision applications where low offset voltage and low power are critical.  
- The device features high CMRR and PSRR, making it suitable for instrumentation and signal conditioning.  

### **Features:**
- **Low Power Consumption:** 500µA per amplifier.  
- **Rail-to-Rail Output Swing:** Ensures maximum dynamic range.  
- **Low Input Offset Voltage:** 300µV typical for precision applications.  
- **Wide Supply Range:** Operates from ±1.25V to ±15V (dual supply) or 2.5V to 30V (single supply).  
- **High CMRR and PSRR:** Minimizes errors in noisy environments.  
- **Stable with Capacitive Loads:** Designed for driving capacitive loads without oscillation.  

The LT1491AIN is commonly used in battery-powered systems, sensor interfaces, and precision signal processing circuits.
