DESCRIPTION
The NJM8080 is dual operational amplifier designed for
audio applications. NJM8080 finely refines to every detail
from Si-wafer to circuit layout, stick in a thorough
improvement in sound quality. The NJM8080 features high
resolution and crispy-clear high frequency sound, which
can fully perform the digital sound source with loss-less.
NJM8080 features low noise, wide gain-bandwidth, low
distortion and high output current, and various reliabilities
and conveniences are improved. NJM8080 can widely be
used as the standard audio operational amplifier.

(1) Differential voltage is the voltage difference between +INPUT and -INPUT.
+.
(2) Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of V
The normal operation will establish when any input is within the “Common-Mode Input Voltage Range” of electrical characteristics.
(3) Power dissipation is the power that can be consumed by the IC at Ta=25ºC, and is the typical measured value based on JEDEC
condition.
(4) 2-Layer: Mounted on glass epoxy board. (76.2×114.3×1.6 mm: based on EIA/JDEC standard, 2-layer FR-4)
4-Layer: Mounted on glass epoxy board. (76.2×114.3×1.6 mm: based on EIA/JDEC standard, 4-layer FR-4), internal Cu area: 74.2 x
