DS3508
I2C, 8-Channel Gamma Buffer with EEPROM
8
_______________________________________________________________________________________
On power-up, the gamma data that is stored in each
channel’s EEPROM register is loaded into the corre-
sponding SRAM registers. The volatile CR register pow-
ers up as 00h, setting the device into mode 0.
DAC Description
The DACs are composed of a resistor string array and
a switching network per channel. A high-voltage array
with end points VHH and VHM controls outputs
GM1–GM4, and a low-voltage array with end points
VLM and VLL controls outputs GM5–GM8. The resistor
string arrays are composed of 255 identical resistors.
The switching networks can select any tap point
between adjacent resistors as well as either end point
(VHH/VHM or VLM/VLL pins). Table 1 shows the rela-
tionship between the 8-bit data and the DAC voltage.
