LM4562
Dual High Performance, High Fidelity Audio Operational
Amplifier
General 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.
Combining advanced leading-edge process technology with
state-of-the-art circuit design, the LM4562 audio operational
amplifiers deliver superior audio signal amplification for out-
standing audio performance. The LM4562 combines ex-
tremely low voltage noise density (2.7nV/
√Hz) with vanish-
ingly 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 LM4562
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 2k
loads to within 1V of either power
supply voltage and to within 1.4V when driving 600
loads.
The LM4562's outstanding CMRR (120dB), PSRR (120dB),
and V
OS (0.1mV) give the amplifier excellent operational am-
plifier DC performance.
The LM4562 has a wide supply range of ±2.5V to ±17V. Over
this supply range the LM4562’s input circuitry maintains ex-
cellent 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 out-
standing AC performance while driving complex loads with
values as high as 100pF.
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.
