AIN6 V
HIGH
Limit Register (Read/Write) [Address = 33h]
This limit register is an 8-bit read/write register that stores the
AIN3 input upper limit that causes an interrupt and activates
the INT/
INT
output (if enabled). For this to happen, the
measured AIN6 value has to be greater than the value in this
register. Because it is an 8-bit register, the resolution is four
times less than the resolution of the 10-bit ADC. The default
value is full-scale voltage.

AIN6 V
LOW
Limit Register (Read/Write) [Address = 34h]
This limit register is an 8-bit read/write register that stores the
AIN6 input lower limit that causes an interrupt and activates
the INT/
INT
output (if enabled). For this to happen, the
measured AIN6 value has to be less than or equal to the value in
this register. Because it is an 8-bit register, the resolution is four
times less than the resolution of the 10-bit ADC. The default
value is 0 V.

AIN7 V
HIGH
Limit Register (Read/Write) [Address = 35h]
This limit register is an 8-bit read/write register that stores the
AIN7 input upper limit that causes an interrupt and activates
the INT/
INT
output (if enabled). For this to happen, the
measured AIN7 value has to be greater than the value in this
register. Because it is an 8-bit register, the resolution is four
times less than the resolution of the 10-bit ADC. The default
value is full-scale voltage.

LOW
Limit Register (Read/Write) [Address = 36h]
This limit register is an 8-bit read/write register that stores the
AIN7 input lower limit that causes an interrupt and activates
the INT/

output (if enabled). For this to happen, the
measured AIN7 value has to be less than or equal to the value in

times less than the resolution of the 10-bit ADC. The default
value is 0 V.

AIN8 V
HIGH
Limit Register (Read/Write) [Address = 37h]
This limit register is an 8-bit read/write register that stores the
AIN8 input upper limit that causes an interrupt and activates
the INT/
INT
output (if enabled). For this to happen, the
measured AIN8 value has to be greater than the value in this
register. As it is an 8-bit register, the resolution is four times less
than the resolution of the 10-bit ADC. The default value is full-
scale voltage.

Device ID Register (Read-Only) [Address = 4Dh]
This 8-bit read-only register gives a unique identification
number for this part. ADT7411 = 02h.
Manufacturer’s ID Register (Read-Only) [Address = 4Eh]
This register contains the manufacturer’s identification number.
Analog Devices, Inc. is 41h.
Silicon Revision Register (Read-Only) [Address = 4Fh]
This register is divided into the four LSBs representing the
stepping and the four MSBs representing the version. The
stepping contains the manufacturer’s code for minor revisions
or steppings to the silicon. The version is the ADT7411 version
number, 0100b (4h).
