The ADD8504, ADD8505, and ADD8506 are 4-, 5-, and 6-channel LCD gamma reference buffers designed to drive column driver gamma inputs in line inversion panels. Each buffer channel has an A/B input to select between two gamma voltage curves. These buffer channels drive the resistor ladders of LCD column drivers for gamma correction. The ADD8504/ ADD8505/ADD850.
Single-supply operation: 3.3 V to 6.5 V Rail-to-rail input, rail-to-rail output High output current: 380 mA Low supply current: 3.9 mA Stable with 1 nF loads Wide temperature range: −40°C to +105°C 16-, 20-, and 24-lead, Pb-free, TSSOP packages PIN CONFIGURATION DIAGRAMS INA1 1 INB1 2 INA2 3 INB2 4 INA3 5 INB3 6 INA4 7 INB4 8 16 15 14 13 12 11 10 9 OUT1 OUT2 VCC1 A/B GND GND 05549-001 05549-003 05549-002 OUT3 OUT4 APPLICATIONS LCD line inversion gamma references Car navigation panels Personal media player panels INA1 1 INB1 2 INA2 3 20 VCC1 19 OUT1 18 OUT2 17 OUT3 16 VCC2 15 A/B 14 GND 13 .
