DESCRIPTION
NJM8068 is a low noise bipolar input dual audio
operational amplifier has 3.5 nV/√Hz at 1kHz.
The NJM8068 features Low distortion, high slew rate, wide
bandwidth and high open-loop gain. In addition, unity-gain
stable allows voltage-follower operation. These features
make NJM8068 ideal for audio pre amplifier, microphone
amplifier, line amplifier and other audio applications.
NJM8068 operate over a wide temperature range of -40°C
to 125°C, making this IC ideal for use in industrial
measurement instruments
The NJM8068 is available in 8-pin SOP and MSOP
(TVSP) packages.

(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=25°C, and is the typical measured value based on JEDEC
condition.
