AD8511 - Muxed Input LCD Reference Buffers

Description

The AD8509 and AD8511 are 9-channel and 11-channel LCD reference buffers, respectively, designed to drive 64 gray scale column drivers.

Each buffer has an A/B input to select between two voltages for LCD displays.

These buffers drive the resistor ladders of LCD column drivers for gamma correction.

Features

  • Single-supply operation: 3.3 V to 6.5 V High output current: 300 mA Low supply current: 6 mA Stable with 1000 pF loads Pin compatible with LMC6009 Pin compatible with CL-FP6131 48-lead, Pb-free TSSOP/LFCSP packages.

Each buffer has an A/B input to select between two voltages for LCD displays. These buffers drive the resistor ladders of LCD column drivers for gamma correction. The LCD drivers have higher slew rates and higher output drive currents than similar competitive parts.
