ADD8502 - Integrated LCD Grayscale Generator

Description

The ADD8502 is an integrated, high accuracy, programmable grayscale generator.

Two sets of five output reference voltages are mask programmed to 0.2% resolution.

The outputs switch between the two sets of five levels.

Features

  • Two Mask Programmable Sets of Five Reference Levels Dual 10-Bit DACs for Flicker Offset and Range Adjustment Integrated VCOM Switching Single-Supply Operation: 5.0 V Low Supply Current: 300 ␮ A Global Power Save Mode: 1 ␮A Max Fast Settling Time for Load Change: 20 ␮ s Stable with 20 nF/100 ⍀ Loads CMOS/TTL Input Levels.
