The LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LM4562 bines extremely low voltage noise density (2.7n V/√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 promise, the LM4562 has a high slew rate of ±20V/μs and an output current capability of ±26m A. 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 (120d B), PSRR (120d B), and VOS (0.1m V) 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 mon-mode and power supply rejection, as well as maintaining its low input bias current. The LM4562 is unity gain...
