Overview
The LM4562MA/NOPB is a dual high-performance, high-fidelity audio operational amplifier produced by Texas Instruments. It is part of the ultra-low distortion, low noise, high slew rate operational amplifier series, optimized and fully specified for high-performance, high-fidelity applications. The LM4562 combines extremely low voltage noise density (2.7nV/√Hz) with vanishingly low THD+N (0.00003%) to satisfy the most demanding audio applications. It features a high slew rate of ±20V/μs and an output current capability of ±26mA, ensuring it can drive challenging loads without compromise.
