JCV8015 Benefits (1) -- Operational Amp
JCV8015 Benefits (1) -- Operational Amp
Superior Operational Amp for Low Distortion and Low Noise
High Slew Rate
The operational amp comes with a higher slew rate -- two times higher than the previous
types of devices -- to eliminate instantaneous “cross-modulation distortion”.
JCV8015 -- Layout of Parts and Devices
Interference-Free
Layout
The operational amp
features a symmetrical
layout of parts and
devices, which are
completely separated
for left and right
channels. This prevents
signal interference
between the two
channels (see the figure
at right).
