ADT7516/ADT7517/ADT7519
Table 40.
Bit
C2:0 In single-channel mode, these bits select between V
DD
,
the internal temperature sensor, external temperature
sensor/AIN1, AIN2, AIN3, and AIN4 for conversion. The
default is V
DD
.
000 = V
DD
.
001 = Internal temperature sensor.
010 = External temperature sensor/AIN1. (Bits C1:C2 of
the Control Configuration 1 register affect this selection).
011 = AIN2.
100 = AIN3.
101 = AIN4.
110–111 = Reserved.
C3
Reserved.
C4
Selects between single-channel and round robin conver-
sion cycle. The default is round robin.
0 = Round robin.
1 = Single channel.
C5
Default condition is to average every measurement on all
channels 16 times. This bit disables this averaging.
Channels affected are temperature, analog inputs, and
V
DD
.
0 = Enable averaging.
1 = Disable averaging.
C6
SMBus timeout on the serial clock puts a 25 ms limit on
the pulse width of the clock, ensuring that a fault on the
master SCL does not lock up the SDA line.
0 = Disable SMBus timeout.
1 = Enable SMBus timeout.
C7
Software Reset. Setting this bit to 1 causes a software
reset. All registers and DAC outputs will reset to their
default settings.
Control Configuration 3 Register (Read/Write) [Add. =
1Ah]
This configuration register is an 8-bit read/write register that is
used to set up some of the operating modes of the ADT7516/
ADT7517/ADT7519.

Bit Function
C0
Selects between fast and slow ADC conversion speeds.
0 = ADC clock at 1.4 kHz.
1 = ADC clock at 22.5 kHz. D+ and D– analog filters are
disabled.
C1
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.
Bit
Function
0 = 8-bit resolution.
1 = 10-bit resolution.
Reserved. Write 0 only.
0 = LDAC pin controls updating of DAC outputs.
1 = DAC configuration register and LDAC configu ration
register control updating of DAC outputs.
Selects the ADC reference to be either internal V
REF
or V
DD
for analog inputs.
0 = Internal V
REF.
1 = V
DD
.
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.

DAC Configuration Register (Read/Write) [Add. = 1Bh]
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).
