Description

The 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.
