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.
Table 16. CH1OS Register
Bit Location Bit Mnemonic 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.
6 Not Used This bit is unused.
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 be 0 on default.
