EL5211T
60MHz Rail-to-Rail Input-Output Operational Amplifier
EL5211T
The EL5211T is a high voltage rail-to-rail input-output
amplifier with low power consumption. The EL5211T
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 3mA per
amplifier. The EL5211T has an output short circuit
capability of ±300mA and a continuous output current
capability of ±65mA.
The EL5211T 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 amplifiers to offer maximum dynamic range
at any supply voltage. These features make the EL5211T
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 EL5211T is available in a thermally enhanced 8 Ld
HMSOP package, and a thermally enhanced 8 Ld DFN
package. Both feature a standard operational amplifier
pinout. The device operates over an ambient
temperature range of -40°C to +85°C.
