LM6588
TFT-LCD Quad, 16V RRIO High Output Current
Operational Amplifier
General Description
The LM6588 is a low power, high voltage, rail-to-rail input-
output amplifier ideally suited for LCD panel V
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 SO
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.
