In addition to automatic offset calibration, the
MAX1366/MAX1368 offer a user-defined custom offset
16-bit read/write register. The final result of the ADC
conversion is the input after autocalibration minus
ADC Result Register 1 (Read Only)
the value in the custom offset. The custom offset value
is stored in this register. D15 is the MSB. The data is
represented in two’s-complement format.

ADC result register 1 is a 16-bit read-only register. This
register stores the 16 MSBs of the ADC result. The data
is represented in two’s-complement format.
ADC Result Register 2 (Read Only)
For the MAX1366, the data is 16-bit and D15 is the
MSB. For the MAX1368, the data is 12-bit, D15 is the
MSB, and D4 is the LSB.

ADC result register 2 is an 8-bit read-only register. This
register stores the 4 LSBs of the ADC result.
LED Data Register (Read/Write)
Use this result with the result in ADC result register 1 to
form a 20-bit two’s-complement conversion result.

The LED data register is a 16-bit read/write register.
This register updates from ADC result register 1 or from
the serial interface by selecting the SPI/ADC bit in the
control register. The data is represented in two’s-com-
plement format.
For the MAX1366, the data is 16-bit and D15 is the
MSB. For the MAX1368, the data is 12-bit, D15 is the
MSB, and D4 is the LSB, followed by 4 trailing sub-bits.
