The LM4562 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. 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 (2.7nV/
√
^Hz) 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 of ±20V/μs 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 available in 8–lead narrow body SOIC, 8–lead Plastic DIP, and 8–lead Metal Can TO-99. Demonstration boards are
available for each package.
The LM4562 is a Dual High Fidelity Audio Operational Amplifier. This Audio Amplifier offers near zero THD+N and sets a new standard for high end audio users.
National's newest Amplifier uses state of the art circuitry and process to achieve a new class of audio performance and technology. The AC and DC parameters in this amplifier series offers user's a solution well suited for the most demanding signal path applications. There are three package choices to enable all users ease of use and evaluation criteria.
The LM4562 is designed for high slew rate, low noise and high output for systems needing +/-2.5 to +/-17V functionality. The pin out is the National standard to quickly upgrade existing boards. This series is for applications such as high quality audio amplification, multi-media, imaging, line drivers/receivers and active filters. The output current is for 600Ohm loads with more than 26mA drive with THD+N over a wide voltage range.
The LM4562MADB, LM4562NADB and LM4562HADB are evaluation boards designed to establish performance and evaluation to design the best end user system.
The evaluation boards include all components for ready-to-use, a stand-alone bench work.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
