Frequently Asked Questions
What is the LME49723MA and what makes it suitable for audio applications?
The LME49723MA is a high-fidelity, low-noise operational amplifier from Texas Instruments specifically designed for audio applications. It features an ultra-low noise voltage of 2.7 nV/√Hz, which minimizes audible hiss and interference in signal chains. Its wide supply voltage range of ±2.5V to ±17V and unity-gain stability make it versatile for preamplifiers, headphone amplifiers, and other high-performance audio circuits.
What is the supply voltage range supported by the LME49723MA?
The LME49723MA supports a wide supply voltage range of ±2.5V to ±17V (single supply: 5V to 34V). This flexibility allows it to be used in both battery-powered portable audio devices and high-voltage benchtop or professional audio equipment.
Is the LME49723MA unity-gain stable?
Yes, the LME49723MA is unity-gain stable, meaning it can be used in voltage-follower (buffer) configurations without oscillation. This is an important characteristic for driving capacitive loads and interfacing between circuit stages in audio signal chains.
