DAC Configuration Register (Read/Write) [Address = 0x1B]
This configuration register is an 8-bit read/write register that is
used to control the output ranges of all four DACs and also to
control the loading of the DAC registers if the LDAC pin is
disabled (Bit C3 = 1, Control Configuration 3 register).

Function
Selects between fast and slow ADC conversion speeds.
On the ADT7516 and ADT7517, this bit selects between
8-bit and 10-bit DAC output resolution on the thermal
voltage output feature. The default is 8 bits. This bit has no
effect on the ADT7519 output because this part has only
an 8-bit DAC. For the ADT7519, write 0 to this bit.
Reserved. Write 0 only.
0 = LDAC pin controls updating of DAC outputs.
1 = DAC configuration register and LDAC configuration
register control updating of DAC outputs.
Selects the ADC reference to be either internal V
for analog inputs.
Setting this bit selects DAC A voltage output to be
proportional to the internal temperature measurement.
Setting this bit selects DAC B voltage output to be
proportional to the external temperature measurement.
Reserved. Write 0 only.
0 = ADC clock at 1.4 kHz.
1 = ADC clock at 22.5 kHz. D+ and D– analog filters are
disabled.
0 = 8-bit resolution.
1 = 10-bit resolution.
0 = internal V
1 = V

LDAC Configuration Register (Write-Only)[Address = 0x1C]
This configuration register is an 8-bit write register that is used
to control the updating of the quad DAC outputs if the LDAC
pin is disabled and Bits[D4:D5] of the DAC configuration
register are both set to 1. Also selects either the internal or the
external V
self-clearing, that is, reading back from this register always gives
0s for these bits.

Function
00 = MSB write to any DAC register generates LDAC
command that updates that DAC only.
01 = MSB write to DAC B or DAC D register generates
LDAC command that updates DAC A and DAC B or
DAC C and DAC D, respectively.
10 = MSB write to DAC D register generates LDAC
command that updates all four DACs.
11 = LDAC command generated from LDAC register.
Reserved. Write 0s only.
Function
Writing a 1 to this bit generates the LDAC command
to update DAC A output only.
Writing a 1 to this bit generates the LDAC command
to update DAC B output only.
Writing a 1 to this bit generates the LDAC command
to update DAC C output only.
Writing a 1 to this bit generates the LDAC command
to update DAC D output only.
Selects either internal V
