• Manufacturer: Maxim Integrated

6/8/10-Channel, 10-Bit, Nonvolatile Programmable
Gamma and VCOM Reference Voltages
The I
With the increase in DAC resolution from 8 bits to 10
bits, 2 bytes must be transferred to get 10 bits.
Therefore, the word size is 2 bytes (16 bits) in the regis-
ter map. Byte order is big endian. The least significant
