INA1 1 20 VCC1 INB1 2 19 OUT1 INA2 3 18 OUT2 INB2 4 17 OUT3 INA3 5 16 VCC2 GENERAL DESCRIPTION INB3 6 15 A/B 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/ADD8506 outputs have high slew rates and output
drives that increase the stability of the reference ladder resulting
in optimal gray scale and visual performance. INA4 7 14 GND INB4 8 13 GND INA5 9 12 OUT4 INB5 10 11 OUT5 The ADD8504/ADD8505/ADD8506 are specified over the
-40В°C to +105В°C temperature range. They are available, respectively, in 16-, 20-, and 24-lead thin shrink small outline (TSSOP),
surface-mount, Pb-free packages. The ADD8506 is also offered
in a leaded TSSOP.
The ADD8506WWARUZR7 is the automotive grade version. 05549-001 PIN CONFIGURATION DIAGRAMS 05549-002 Single-supply operation: 3.3 V to 6.5 V
