Pin No. Mnemonic Description
39 REFIO
Reference Input/Output. This pin serves as the reference input when the internal reference is disabled (that
is, when REFLO is tied to AVDD), or it serves as the 1.2 V reference output when the internal reference is
activated (that is, when REFLO is tied to ACOM). If the internal reference is activated, a 0.1 µ F capacitor to
ACOM is required.
40 FSADJ Full-Scale Current Output Adjust.
42 I
OUTB
B Complementary DAC Current Output. Full-scale current is selected when all data bits are 0s.
43 I
OUTA
DAC Current Output. Full-scale current is selected when all data bits are 1s.
45, 46 AVDD Analog Supply Voltage (3.1 V to 3.5 V).
