NJM4585 Low Noise, Bipolar Input Dual, Audio Operational amplifier DESCRIPTION PACKAGE OUTLINE 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 NJM4585M amplifier, microphone amplifier, line amplifier and other (DMP8) audio applications. NJM4585 operate over a wide temperature range of -40C to +125C, making this IC ideal for use in industrial measurement instruments. The NJM4585 is available in the 8-pin DMP8 packages.

(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=25C, and is the typical measured value based on JEDEC condition. When using the IC over Ta=25C subtract the value mW/C =P /(Tstg(MAX)-25) per temperature.
