The EL5220T is a high voltage rail-to-rail input-output amplifier with low power consumption. The EL5220T contains two amplifiers. Each amplifier exhibits beyond the rail input capability, rail-to-rail output capability and is unity gain stable. The maximum operating voltage range is from 4. 5V to 19V. It can be configured for single or dual supply operation, and typically consumes only 550µA per amplifier. The EL5220T has an output short circuit capability of ±200mA and a continuous output current capability of ±65mA. The EL5220T features a slew rate of 12V/µs. Also, the device provides common mode input capability beyond the supply rails, rail-to-rail output capability, and a bandwidth of 12MHz (-3dB). This enables the amplifiers to offer maximum dynamic range at any supply voltage. These features make the EL5220T an ideal amplifier solution for use in TFT-LCD panels as a VCOM or static gamma buffer, and in High-Speed filtering and signal conditioning applications. Other applications include battery power and portable devices, especially where low power consumption is important. The EL5220T is available in an 8 Ld MSOP package, and a thermally enhanced 8 Ld DFN package. Both feature a standard operational amplifier pinout. The devices operate over an ambient temperature range of -40°C to +85°C.
