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
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.

(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. When using the IC over Ta=25°C subtract the value [mW/°C]=PD/(Tstg(MAX)-25) per temperature.
