LM6588

TFT-LCD Quad, 16V RRIO High Output Current

Operational Amplifier

General Description

Features

The LM6588 is a low power, high voltage, rail-to-rail input-

output amplifier ideally suited for LCD panel V_COMdriver 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.

complementary bipolar VIP10 technology for high

performance at low power levels

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.

Applications

n LCD panel V_COMdriver

n LCD panel gamma buffer
