N/A means not applicable.

Not a physical register.

VINx Offset Registers (Register 0x10 to Register 0x13)

These read/write 8-bit registers store the offset values for the

relevant input channel.

Temperature Sensor (TSENSEx) Offset Registers

(Register 0x20 to Register 0x22)

These read/write 8-bit registers store the offset values for the

relevant temperature sensor channel.

Current Sensor (ISENSEx) Offset Registers (Register 0x28 to

These read/write 8-bit registers store the offset values for the

relevant current sensor channel.

Unipolar DAC (UNI-VOUTx) Offset Registers (Register 0x30

to Register 0x33)

These read/write registers store the offset values for the

corresponding DAC output. If the copy bit is set to 1, writing to

any of the DAC offset registers sets all the other unipolar DAC

offset registers to the same value.

Bipolar DAC (BI-VOUTx) Offset Registers (Register 0x34 to

These read/write registers store the offset values for the

corresponding DAC output. If the copy bit is set to 1, writing to

any of the DAC offset registers sets all the other bipolar DAC

offset registers to the same value. Any write to these registers

affects the DAC range in open-loop mode and the integrator

limit in closed-loop mode.
