Здравствуйте!
Недавно своему хорошему знакомому заменил операционные усилители
в звуковой карте ??4558 на LM4562, по его словам звук стал естественнее.
Сейчас он заказывает LM4562 для апгрейда рессивера Ямаха.

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 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.
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. This Audio Operational Amplifier achieves outstanding
AC performance while driving complex loads with
values as high as 100pF.
И дана схемка корректора
Конечно на народный эта схема не претендует, но мне она понравилась
вместе с характеристиками ОУ.
Какие будут мнения?
