ADT7516/ADT7517/ADT7519
DAC D Register LSBs (Read/Write) [Add. = 16h]
This 8-bit read/write register contains the 4/2 LSBs of the
ADT7516/ADT7517 DAC D word, respectively. The value in
this register is combined with the value in the DAC D register
MSBs and converted to an analog voltage on the VOUT-D pin.
On power-up, the voltage output on the VOUT-D pin is 0 V.

DAC D Register MSBs (Read/Write) [Add. = 17h]
This 8-bit read/write register contains the eight MSBs of the
DAC D word. The register value combines with the value in the
DAC D register LSBs and converts to an analog voltage on the
VOUT-D pin. On power-up, the voltage output on the VOUT-D pin
is 0 V.

Control Configuration 1 Register (Read/Write)
[Add. = 18h]
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 This bit enables/disables conversions in round robin
and single-channel mode. ADT7516/ADT7517/ADT7519
powers up in round robin mode but monitoring is not
initiated until this bit is set. The default = 0.
0 = Stop monitoring.
1 = Start monitoring.
C2:C1 Selects between the two different analog inputs on Pins
7 and 8. ADT7516/ADT7517/ADT7519 powers up with
AIN1 and AIN2 selected.
00 = AIN1 and AIN2 selected.
01 = Undefined.
10 = External TDM selected.
11 = Undefined.
C3 Selects between digital (LDAC) and analog inputs (AIN3)
on Pin 9. When AIN3 is selected, Bit C3 of the Control
Configuration 3 register is masked and has no effect
until LDAC is selected as the input on Pin 9.
0 = LDAC selected.
1 = AIN3 selected.
C4 Reserved. Write 0 only.
C5 0 = Enable INT/INT output.
1 = Disable INT/INT output.
C6 Configures INT/INT output polarity.
0 = Active low.
1 = Active high.
PD Power-Down Bit. Setting this bit to 1 puts the
ADT7516/ADT7517/ADT7519 into standby mode. In this
mode, both ADC and DACs are fully powered down, but
the serial interface is still operational. To power up the
part again, just write 0 to this bit.
Control Configuration 2 Register (Read/Write)
[Add. = 19h]
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.
