MEMORY MAP REGISTER DESCRIPTIONS
For more information about functions controlled in Register 0x00
to Register 0xFF, see the
to High Speed ADCs via SPI.
Voltage Reference (Register 0x18)
Bits[7:5]—Reserved
Bits[4:0]—Voltage Reference
Bits[4:0] scale the internally generated voltage reference and,
consequently, the full scale of the analog input. Within this register,
the reference driver can be configured to be more easily driven
externally by reducing the capacitive loading.
The relationship between the V
scale is described by Equation 7. See Table 14 for a complete list
of register settings.
