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.
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
The LM4562 is available in an 8-lead narrow body SOIC, an 8-lead PDIP, and an 8-lead
