Quote:As DAC performance has continued to evolve, spearheaded by products such as AKM’s AK4499EX, audio designers have found a dearth of op amps that can leverage these aural advances. AKM’s AK491x series delivers upgraded audio performance, with ultra-low noise and distortion characteristics—noise density of 0.96 nV/√Hz and THD+N of −150 dB at 1 kHz—that are unachievable with conventional op amps. An ample ±100 mA output-drive capability enables these new devices to maintain excellent THD+N characteristics even under the most demanding load conditions, such as 8-channel current summing in DAC applications.
Samples of the AK491x series op amps are currently available, mass production scheduled to start in early 2027.
