National LM4562NA High Performance Dual Audio Op Amp IC
Up to 9 Reward Points
Usually ships in 1-2 business days
The LM4562 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimised and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance.
The LM4562 combines extremely low voltage noise density with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LM4562 has a high slew rate and an output current capability of +/-26mA. Further, dynamic range is maximized by an output stage that drives 2kΩ loads to within 1V of either power supply voltage and to within 1.4V when driving 600Ω loads. The LM4562's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance. The 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 LM4562 is one of the recommended replacement op amps for the following sound cards :-
Auzentech X-Plosion 7.1 DTS and DDL Sound Card
Auzentech X-Meridian 7.1 DTS and DDL Sound Card
Each sound card contains one or more replaceable op amps, mounted in IC sockets for easy replacement. Simply remove the old op amps from the IC sockets, noting the correct orientation for pin 1, and carefully insert the new LM4562 op amps in their place.
