DATA: Data Register
The data register is a 24-bit read-only register. Any attempt to write data to the data register has no effect. The data
read from this register is clocked out MSB first. The data register holds the conversion result. D23 is the MSB, and D0
is the LSB. The result is stored in a format according to the FORMAT bit in CTRL1 register.
The data format while in unipolar mode is always straight binary. In straight binary format, the most negative value is
0x000000 (VAINP - VAINN = 0V), the midscale value is 0x800000 (VAINP - VAINN = VREF/2), and the most positive value
is 0xFFFFFF (VAINP - VAINN = VREF).
In bipolar mode, if the FORMAT bit = 1, then the data format is offset binary. If the FORMAT bit = 0, then the data for-
mat is two’s complement. In two’s complement, the negative full-scale value is 0x800000 (VAINP - VAINN = -VREF), the
midscale is 0x000000 (VAINP - VAINN = 0V), and the positive full scale is 0x7FFFFF (VAINP - VAINN = VREF). Any input
exceeding the available input range is limited to the minimum or maximum data value.
