CH1OS REGISTER (0x0D)

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

Channel 1, and Bits 0 to 5 indicate the amount of offset correction in Channel 1. Table 13 summarizes the function of this register.

Description

0 to 5

OFFSET

The 6 LSBs of the CH1OS register control the amount of dc offset correction in the 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.

7

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 0 by default.
