POWER-ON STATE
circuit ensures that all registers are loaded with zero code. As
such, the output is disabled (tristate). Also upon power-on,
internal calibration registers are read, and the data is applied to
internal calibration circuitry. For a reliable read operation, there
must be sufficient voltage on the AVDD supply when the read event
is triggered by the DVCC power supply powering up. Powering
up the DVCC supply after the AVDD supply ensures this. If DVCC
and AVDD are powered up simultaneously or if the internal DVCC
is enabled, the supplies should be powered up at a rate greater
than, typically, 500 V/sec or 24 V per 50 ms. If this cannot be
after power-on. This performs a power-on reset event, reading
the calibration registers and ensuring specified operation of the
TRANSFER FUNCTION

current output ranges, the output current is respectively

is the bit resolution of the DAC.
DATA REGISTER
The data register is addressed by setting the address byte of the
input shift register to 0x01. The data to be written to the data
register is entered in Position DB15 to Position DB4 for the
as shown in Table 12 and Table 13, respectively.
CONTROL REGISTER
The control register is addressed by setting the address byte of
the input shift register to 0x55. The data to be written to the
control register is entered in Position DB15 to Position DB0,
as shown in Table 14. The control register bit functions are
described in Table 10.

Bit
Description
REXT
Setting this bit selects the external current setting
for further details. When using an external current
setting resistor, it is recommended to only set REXT
when also setting the OUTEN bit. Alternately, REXT
can be set before the OUTEN bit is set, but the range
(see Table 11) must be changed on the write in which
the output is enabled. See Figure 40 for best practice.
OUTEN
Output enable. This bit must be set to enable the
output.
