SBOS438C – AUGUST 2008 – REVISED AUGUST 2009 APPLICATION INFORMATION At power-on, the BUF08821 first updates all channels to midscale (code 1000000000) and then reads the GENERAL data for both memory banks into the two sets of The BUF08821 programmable voltage reference storage registers. This read process requires allows fast and easy adjustment of eight approximately 560 μs. After this read is complete, the programmable gamma reference outputs and one BUF08821 updates the DACs simultaneously with VCOM output, each with 10-bit resolution. The data for the bank selected by the BKSEL pin. BUF08821 is programmed through a high-speed, I2C The BUF08821 can be powered using an analog interface. The final gamma and VCOM values can be supply voltage from 9V to 20V, and a digital supply stored in the on-chip, nonvolatile memory. To allow from 2V to 5.5V. The digital supply must be applied for programming errors or liquid crystal display (LCD) before the analog supply to avoid excessive current panel rework, the BUF08821 supports up to 16 write and power consumption, or possibly even damage to operations to each word in the on-chip memory. The the device if left connected only to the analog supply BUF08821 has two separate memory banks, allowing for extended periods of time. Figure 10 shows a simultaneous storage of two different gamma curves typical configuration of the BUF08821. to facilitate dynamic switching between gamma curves. The BUF08821 also has two storage registers for each digital-to-analog converter (DAC) channel to allow fast switching (less than 10 μs) between gamma curves. (1) RC combination optional; see the Output Pins ESD Protection Current-Steering Diodes section. (2) GNDA and GNDD must be connected together. (3) Pins 6 and 15 are VS. The one set of capacitors shown on pin 15 are common to both pins. Figure 10.
