CH1OS REGISTER (0x0D)

The CH1OS register is an 8-bit, read/write enabled register. The MSB of this register is used to switch on/off the digital integrator in

Channel 1, and Bits 0 to 5 indicates the amount of the offset correction in Channel 1. Table 16 summarizes the function of this register.

Description

0 to 5

OFFSET

The six LSBs of the CH1OS register control the amount of dc offset correction in Channel 1 ADC. The

6-bit offset correction is sign and magnitude coded. Bits 0 to 4 indicate the magnitude of the offset

correction. Bit 5 shows the sign of the offset correction. A 0 in Bit 5 means the offset correction is

positive and a 1 indicates the offset correction is negative.

Not Used

This bit is unused.

INTEGRATOR

This bit is used to activate the digital integrator on Channel 1. The digital integrator is switched on by

setting this bit. This bit is set to be 0 on default.
