DB11
DB10–DB1 Data Bits 1–10.
DB0
Least Significant Data Bit (LSB).
No Internal Connection.
SLEEP
Power-Down Control Input. Active High. Contains active pull-down circuit, thus may be left unterminated
if not used.
REFLO
Reference Ground when Internal 1.2 V Reference Used. Connect to AVDD to disable internal reference.
REFIO
Reference Input/Output. Serves as reference input when internal reference disabled (i.e., Tie REFLO to
AVDD). Serves as 1.2 V reference output when internal reference activated (i.e., Tie REFLO to ACOM).
Requires 0.1
μ
F capacitor to ACOM when internal reference activated.
FS ADJ
Full-Scale Current Output Adjust.
