Gain Register
The 16-bit gain register, as shown in Table 11, allows the user to
adjust the gain of each channel in steps of 1 LSB. This is done by
setting the DREG[2:0] bits to 010. It is possible to write the
same gain code to all four DAC channels at the same time by
setting the DREG[2:0] bits to 011. The gain register coding is
straight binary as shown in Table 12. The default code in the
gain register is 0xFFFF. In theory, the gain can be tuned across
the full range of the output. In practice, the maximum
recommended gain trim is about 50% of programmed range to
maintain accuracy. See the Digital Offset and Gain Control
section for more information.
Offset Register
The 16-bit offset register, as shown in Table 13, allows the user to
adjust the offset of each channel by 32,768 LSBs to +32,767 LSBs
in steps of 1 LSB. This is done by setting the DREG[2:0] bits to
100. It is possible to write the same offset code to all four DAC
channels at the same time by setting the DREG[2:0] bits to 101.
The offset register coding is straight binary as shown in Table 14.
The default code in the offset register is 0x8000, which results in
zero offset programmed to the output. See the Digital Offset
and Gain Control section for more information.
Clear Code Register
The 16-bit clear code register allows the user to set the clear
value of each channel as shown in Table 15. It is possible, via
software, to enable or disable on a per channel basis which
channels are cleared when the CLEAR pin is activated. The
default clear code is 0x0000. See the Asynchronous Clear
section for more information.
