+5V, 18-Bit, Low-Power, Multichannel,
Oversampling (Sigma-Delta) ADC
The data register is a 24-bit, read-only register. Any
attempt to write data to this location will have no effect.
If a write operation is attempted, 8 bits of data must be
clocked into the part before it will return to its normal
idle mode, expecting a write to the communications
register.
Data is output MSB first, followed by one reserved 0 bit,
two auxiliary data bits, and a 3-bit channel ID tag indi-
cating the channel from which the data originated.

D17–D0: The conversion result. D17 is the MSB. The
result is in offset binary format. 00 0000 0000 0000
0000 represents the minimum value and 11 1111 1111
1111 1111 represents the maximum value. Inputs
exceeding the available input range are limited to the
corresponding minimum or maximum output values.
0: This reserved bit will always be 0.
