1 Low Noise, Bipolar Input Dual, Audio Operational amplifier DESCRIPTION NJM48 is a low noise bipolar input dual audio operational amplifier featuring.nv/ Hz at khz. The NJM48 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 NJM48 ideal for audio pre amplifier, microphone amplifier, line amplifier and other audio applications. NJM48 operate over a wide temperature range of -4 C to + C, making this IC ideal for use in industrial measurement instruments. The NJM48 is available in the 8-pin DMP8 packages.
