The EL5420T is a low power, high voltage rail-to-rail
input-output amplifier. The EL5420T contains four 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 500µA per amplifier. The EL5420T
has an output short circuit capability of ±200mA and a
continuous output current capability of ±70mA.
The EL5420T 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 EL5420T 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 EL5420T is available in a 14 Ld TSSOP package,
14 Ld SOIC package, and a space saving thermally
enhanced 16 Ld QFN package. All feature a standard
operational amplifier pin out. The devices operate over an
ambient temperature range of -40°C to +85°C.
