See the preview image and the PDF file for more information.
The i7824DA is a rail-to-rail quad channels operational amplifier with wide supply range from 4.5V to 18V while consumes only 500uA per channel. It provides 0.5V beyond the supply rails of common mode input range and capability of rail-to-rail output swing as well. This enables the amplifier to offer maximum dynamic range at any supply voltage among many applications. A 3.5MHz gain bandwidth product allows i7824DA to perform more stable than other devices in Internet applications.
