NOTES: 1. All parameters pertain to each SD16_A channel.
2. The analog input range depends on the reference voltage applied to V
REF
. If V
REF
is sourced externally, the full-scale range
is defined by V
FSR+
= +(V
REF
/2)/GAIN and V
FSR−
= −(V
REF
/2)/GAIN. The analog input range should not exceed 80% of
V
FSR+
or V
FSR−
.
