The conversion data are 24 bits, in two's-complement format to represent positive and negative values. The data begins with the most significant bit (sign bit) first. The data are scaled so that VIN = 0 V results in an ideal code value of 000000h, the positive full-scale input is equal to an ideal value of 7FFFFFh and the negative full-scale input is equal to an ideal code value of 800000h. Table 15 shows the code values. The data are clipped to 7FFFFFh and 800000h during positive and negative signal overdrive, respectively.
|DESCRIPTION||INPUT SIGNAL (V)||24-BIT CONVERSION DATA(1)|
|Positive full scale||≥ VREF / Gain × (223 – 1) / 223||7FFFFFh|
|1 LSB||VREF / (Gain × 223 )||000001h|
|–1 LSB||–VREF / (Gain × 223 )||FFFFFFh|
|Negative full scale||≤ –VREF / Gain||800000h|
