PRODUCTION DATA.
The conversion data are 24 bits, in two's-complement format to represent positive and negative values. The data output begins with the most significant bit (sign bit) first. The data are scaled so that VIN = 0 V results in an uncalibrated code value of 000000h; positive full scale equals 7FFFFFh and negative full scale equals 800000h; see Table 13 for the uncalibrated code values. The data are clipped to 7FFFFFh (positive full scale) and 800000h (negative full scale) 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 |
Zero scale | 0 | 000000h |
-1 LSB | –VREF / (Gain · 223 ) | FFFFFFh |
Negative Full Scale | ≤ –VREF / Gain | 800000h |
