... V Power CC Detailed Description The DS3508 provides eight independent DACs that allow precise and repeatable setting of gamma curves. The DS3508 provides four high-voltage DACs (GM1–GM4) that operate between VHH and VHM and four low-voltage DACs (GM5–GM8) that operate between VLM and VLL. Each of the DACs provides 8 bits of resolution ...

I C, 8-Channel Gamma Buffer with EEPROM 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 ...

... START condition, writes the slave address byte (R/W = 0), writes the starting memory address, writes data bytes, and generates a STOP condition. The DS3508 can write bytes (1 page or row single write transaction. This is internally controlled by an address counter that allows data to be written to consecutive addresses without transmitting a memory address before each data byte is sent ...

... STOP condition. The master must NACK the last byte to inform the slave that no additional bytes are to be read. Applications Information Power-Supply Decoupling To achieve the best results when using the DS3508, decouple both power-supply pins (V 0.01µF or 0.1µF capacitor. Use a high-quality ceramic surface-mount capacitor if possible. Surface-mount Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product ...
