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.

Mnemonic 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.
6 Not Used This bit is not used.
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.
