ADD8504: 4-Channel Buffer GENERAL DESCRIPTION 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. The ADD8504/ADD8505/ADD8506 are specified over the −40°C to +105°C temperature range. They are available, respectively, in 16-, 20-, and 24-lead thin shrink small outline (TSSOP), surface-mount, Pb-free packages. INB2 4 INA3 5 INB3 6 INA4 7 INB4 8 INA5 9 INB5 10 Figure 2.

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.

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. 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. 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. Table 6.
