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.
The DS3508 DAC output voltages are independently
controlled by the data stored in that channel’s SRAM
register. The MODE bit in the volatile control register
(CR bit 7) determines how I2C data is written to the
SRAM and EEPROM gamma data registers. Reading
and writing to the SRAM/EEPROM gamma data regis-
ters is based on the state of the MODE bit as follows:
MODE = 0:
I2C writes to memory addresses
00h–07h write to both SRAM 1–8 and
EEPROM 1–8.
I2C reads from addresses 00h–07h
read from SRAM 1–8.
MODE = 1:
I2C writes to addresses 00h–07h write
to SRAM 1–8.
I2C reads from addresses 00h–07h
read from SRAM 1–8.
Regardless of the MODE bit setting, all I2C reads of
address 00–07h return the contents of the SRAM regis-
ters. Setting MODE = 1 allows for quick writing of SRAM
without the added delay of writing to the associated
EEPROM register. The data that is stored in EEPROM and
SRAM remains unchanged if the MODE bit is toggled.
