LM4562 Datasheet | National Semiconductor

Description 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. bining 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 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 stable. This Audio Operational Amplifier achieves outstanding AC performance while driving plex loads with values as high as 100p F. 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. j THD+N (AV = 1, VOUT = 3VRMS, f IN = 1k Hz) RL = 2kΩ RL = 600Ω j Input Noise Density j Slew Rate j Gain Bandwidth Product j Open Loop Gain (RL = 600Ω) j Input Bias Current j Input Offset Voltage j DC Gain Linearity Error 0.00003% (typ) 0.00003% (typ) 2.7n V/√Hz (typ) ± 20V/µs (typ) 55MHz (typ) 140d B (typ) 10n A (typ) 0.1m V (typ) 0.000009% Features n n n n n Easily drives 600Ω loads Optimized for superior audio signal fidelity Output short circuit...
