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.
