It provides 0.5V beyond the supply rails of commo n 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 20MHz gain bandwidth product allows EC5612 to perform more stable than other devices in Internet applications. With features of 30V/μs high slew rate and 500ns of fast settling time, as well as 100mA (sink and source) of high output driving capability, the EC5612 is ideal for the requirements of flat panel Thin Film Transistor Liquid Crystal Displays (TFT-LCD) panel reference buffers application. Due to insensitive to power supply variation, EC5612 offers flexibility of use in multitude of applications such as battery power, portable devices and anywhere low power consumption is concerned. With standard operational amplifier pin assignm ent, the EC5612 is specified over the -40°C to +85°C temperature range. MSOP 8 / TSSOP-8 SOP 8 1 of 11
