AIN6 VHIGH 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

times less than the resolution of the 10-bit ADC. The default

value is full-scale voltage.

1 Default settings at power-up.

AIN6 VLOW 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 VHIGH 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

times less than the resolution of the 10-bit ADC. The default

value is full-scale voltage.

AIN7 VLOW 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/INT output (if enabled). For this to happen, the

measured AIN7 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.

AIN8 VHIGH 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

than the resolution of the 10-bit ADC. The default value is full-

scale voltage.

AIN8 VLOW Limit Register (Read/Write) [Address = 38h]

This limit register is an 8-bit read/write register that stores the

AIN8 input lower limit that causes an interrupt and activates

the INT/INT output (if enabled). For this to happen, the

measured AIN8 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.

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).
