bit 15

bit 0

Legend:

R = Readable bit

W = Writable bit

C = Clearable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

= Single-channel device

= Dual-channel device

bit 15-10

Unimplemented: Read as ‘0’

bit 9-8

GX(1): DAC Output Driver Gain control bits

1 = 2X Gain

0 = 1X Gain

bit 7-0

Unimplemented: Read as ‘0’

Note 1:

When the DAC Voltage Reference is selected as VDD (VRxB:VRxA = “00”), the DAC’s Gain bit is ignored

and the gain is forced to 1X (GX = “0”).
