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. ■ FEATURES ●Operating Voltage ●Rail-to-Rail Output ■PACKAGE INFORMATION NJM2746KU1 ( ESON8 ) NJM2746M ( DMP8 ) 2.5V to 14V VOH ≥4.9V Typ.
