■ DESCRIPTION
NJM4585 is a low noise bipolar input dual audio
operational amplifier featuring 3.5nV/√Hz at 1 kHz.
The NJM4585 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 NJM4585 ideal for audio pre
amplifier, microphone amplifier, line amplifier and other
audio applications. NJM4585 operate over a wide
temperature range of -40°C to +125°C, making this IC
ideal for use in industrial measurement instruments.
The NJM4585 is available in the 8-pin DMP8 packages.
