www.ti.com SNAS427A – APRIL 2008 – REVISED APRIL 2013 LME49725 PowerWise® Dual High Performance, High Fidelity Audio Operational Amplifier
Check for Samples: LME49725 FEATURES DESCRIPTION The LME49725 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 LME49725 audio operational
amplifiers deliver superior audio signal amplification
for outstanding audio performance. The LME49725
combines extremely low voltage noise density
(3.3nV/в€љHz) with vanishingly low THD+N (0.00004%)
to easily satisfy the most demanding audio
applications. To ensure that the most challenging
loads are driven without compromise, the LME49725
has a high slew rate of В±15V/Ојs and an output current
capability of В±22mA. 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. 1 2 Optimized for Superior Audio Signal Fidelity
