NJM2746
Single Supply, Rail-to-Rail Output Dual Operational Amplifier
■GENERAL DESCRIPTION
The NJM2746 is a Rail-to-Rail Output single supply dual operational
amplifier with a low noise of 10nV/√Hz.
It has an output voltage swing closer to the rails, which can offer a
wide dynamic range of output voltage easer compared with
conventionally single supply operational amplifiers.
And Input voltage range extended from ground level makes it
suited for single supply operation. The NJM2746 is suitable for
various amplifiers and filters using in sound processing, signal
detection and other applications. The NJM2746 is available in a wide
variety of packages, SOP8 (DMP8), SOP8 JEDEC 150 mil, SSOP8,
MSOP8 (TVSP8) and a small lead-less 2020 size package of
ESON8 which allows high-density mounting.
