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.

Input bias currents are orders of magnitude less than competitive parts. This allows the use of a very large resistor ladder to save supply current. Power supply pins on the ADD8505 and ADD8506 have multiple ground (GND) and supply (VCC) connections. Because of the high peak currents that these buffers deliver, it is recommended that all GND and VCC pins be connected and suitably bypassed. The buffer outputs are designed to drive resistive or capacitive loads. Therefore, to attain the best display performance, do not use resistors in series with these outputs. Outputs have high slew rates and 6 μs settling times. Each output delivers a minimum of 120 mA, ensuring a fast response to varying loads. Table 6.
