DESCRIPTION
The LM6588 is a low power, high voltage, rail-to-rail
input-output amplifier ideally suited for LCD panel
VCOM driver and gamma buffer applications. The
LM6588 contains four unity gain stable amplifiers in
one package. It provides a common mode input
ability of 0.5V beyond the supply rails, as well as an
output voltage range that extends to within 50mV of
either supply rail. With these capabilities, the LM6588
provides maximum dynamic range at any supply
voltage. Operating on supplies ranging from 5V to
16V, while consuming only 750μA per amplifier, the
LM6588 has a bandwidth of 24MHz (−3dB).
The LM6588 also features fast slewing and settling
times, along with a high continuous output capability
of 75mA. This output stage is capable of delivering
approximately 200mA peak currents in order to
charge or discharge capacitive loads. These features
are ideal for use in TFT-LCDs.
The LM6588 is available in the industry standard 14-
pin SOIC package and in the space-saving 14-pin
TSSOP package. The amplifiers are specified for
operation over the full −40°C to +85°C temperature
range.
