资料介绍

德州仪器超低噪声音频运放，包含参考电路设计。

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.

FEATURES  
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. 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.  
KEY SPECIFICATIONS

Power Supply Voltage Range: ±2.5V to ± 17V  
THD+N (AV = 1, VOUT = 3VRMS, fIN = 1kHz)  
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.
