SBAS740B October 2015 – May 2020 ADS1118-Q1
PRODUCTION DATA.
The ADS1118-Q1 provides 16 bits of data in binary twos complement format. A positive full-scale (+FS) input produces an output code of 7FFFh and a negative full-scale (–FS) input produces an output code of 8000h. The output clips at these codes for signals that exceed full-scale. Table 5 summarizes the ideal output codes for different input signals. Figure 33 shows code transitions versus input voltage.
INPUT SIGNAL, VIN

---|---|
≥ +FS (215 – 1) / 215 | 7FFFh |
+FS / 215 | 0001h |
0 | 0 |
–FS / 215 | FFFFh |
≤ –FS | 8000h |
