LME49870
44V Single High Performance, High Fidelity Audio
Operational Amplifier
General Description
The LME49870 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 LME49870 audio opera-
tional amplifier delivers superior audio signal amplification for
outstanding audio performance. The LME49870 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 LME49870
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 2kloads to within 1V of either power
supply voltage and to within 1.4V when driving 600loads.
The LME49870's outstanding CMRR (120dB), PSRR
(120dB), and VOS (0.1mV) give the amplifier excellent oper-
ational amplifier DC performance.
The LME49870 has a wide supply range of ±2.5V to ±22V.
Over this supply range the LME49870 maintains excellent
common-mode rejection, power supply rejection, and low in-
put bias current. The LME49870 is unity gain stable. This
Audio Operational Amplifier achieves outstanding AC perfor-
mance while driving complex loads with values as high as
100pF.
The LME49870 is available in 8–lead narrow body SOIC.
Demonstration boards are available for each package.
