    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
