LM4562 is a Dual High-Performance, High-Fidelity Audio Operational Amplifier IC. LM4562 has a wide supply range of ±2.5V to ±17V. Over this supply range the LM4562’s input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LM4562 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The IC comes in an 8 – pin hermetically sealed dual in line IC packaging. LM4562 offers many features such as Superior Audio Signal Fidelity, output short circuit protection, and high noise immunity.
Audio Operational Amplifier
An audio operational amplifier is the core element used in audio amps. It is designed to boost a weak audio signal from a device such as a microphone or a smartphone to an amplitude of higher level, so that the signal is audible to everyone.
