Description and Introduction

Dual High Performance, High Fidelity Audio Operational Amplifier The LME49720HA is a high-performance audio operational amplifier manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Type:** High-fidelity, high-performance audio op-amp  
- **Architecture:** Bipolar (BJT) input  
- **Supply Voltage Range:** ±2.5V to ±17V  
- **Output Current:** ±26mA (typical)  
- **Slew Rate:** 20V/µs (typical)  
- **Gain Bandwidth Product:** 55MHz (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.00003% (1kHz, 600Ω, 3.5V RMS)  
- **Input Noise Voltage:** 2.7nV/√Hz (typical at 1kHz)  
- **Input Bias Current:** 10nA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TO-99 metal can (8-pin)  

### **Descriptions and Features:**  
- **Ultra-Low Distortion:** Designed for high-end audio applications with extremely low THD+N.  
- **Low Noise:** Optimized for minimal noise in sensitive audio circuits.  
- **Wide Bandwidth:** High gain bandwidth ensures accurate signal reproduction.  
- **High Slew Rate:** Enables fast response for dynamic audio signals.  
- **Robust Output Drive:** Capable of driving low-impedance loads.  
- **High PSRR (Power Supply Rejection Ratio):** Reduces power supply noise interference.  
- **Stable Operation:** Unity-gain stable with external compensation.  
- **Metal Can Package (TO-99):** Provides superior thermal performance and shielding.  

The LME49720HA is commonly used in professional audio equipment, DACs, preamplifiers, and high-end headphone amplifiers.
