60MHz Rail-to-Rail Input-Output Operational Amplifier
EL5111T
The EL5111T is a high voltage rail-to-rail input-output
amplifier with low power consumption. The EL5111T is a
single amplifier which 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 3mA. The
EL5111T has an output short circuit capability of
±300mA and a continuous output current capability of
±70mA.
The EL5111T features a high slew rate of 100V/μs, and
fast settling time. Also, the device provides common
mode input capability beyond the supply rails, rail-to-rail
output capability, and a bandwidth of 60MHz (-3dB). This
enables the amplifier to offer maximum dynamic range
at any supply voltage. These features make the EL5111T
an ideal amplifier solution for use in TFT-LCD panels as a
V
COM
driver 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 EL5111T is available in small 5 Ld TSOT package. It
features a standard operational amplifier pinout. The
device operates over an ambient temperature range of
-40°C to +85°C.
