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.
