LME49720  
Dual High Performance, High Fidelity Audio Operational  
Amplifier  
General Description  
RL = 2kΩ  
0.00003% (typ)  
0.00003% (typ)  
2.7nV/√Hz (typ)  
±20V/μs (typ)

RL = 600Ω  
The LME49720 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 LME49720 audio opera-  
tional amplifiers deliver superior audio signal amplification for  
outstanding audio performance. The LME49720 combines  
extremely low voltage noise density (2.7nV/√Hz) with van-  
ishingly low THD+N (0.00003%) to easily satisfy the most  
demanding audio applications. To ensure that the most chal-  
lenging loads are driven without compromise, the LME49720  
has a high slew rate of ±20V/μs and an output current capa-  
bility 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 LME49720's outstanding CMRR (120dB), PSRR  
(120dB), and VOS (0.1mV) give the amplifier excellent oper-  
ational amplifier DC performance.  
Optimized for superior audio signal fidelity  
Output short circuit protection  
PSRR and CMRR exceed 120dB (typ)  
SOIC, DIP, TO-99 metal can packages  
The LME49720 has a wide supply range of ±2.5V to ±17V.  
Over this supply range the LME49720’s input circuitry main-  
tains excellent common-mode and power supply rejection, as  
well as maintaining its low input bias current. The LME49720  
is unity gain stable. This Audio Operational Amplifier achieves  
outstanding AC performance while driving complex loads with  
values as high as 100pF.  
Applications  
Ultra high quality audio amplification
