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.
