a. D/A subsystems are supported by the DT9822 module only.
b. A high-to-low transition on digital input line 0 can trigger A/D subsystem 0; a high-to-low
transition on digital input line 1 can trigger A/D subsystem 1, a high-to-low transition on dig-
ital input line 2 can trigger A/D subsystem 2, and a high-to-low transition on digital input line
3 can trigger A/D subsystem 3.
Similarly, a high-to-low transition on digital input line 4 can stop the A/D operation on sub-
system 0; a high-to-low transition on digital input line 5 can stop the A/D operation on sub-
system 1, a high-to-low transition on digital input line 6 can stop the A/D operation on
subsystem 2, and a high-to-low transition on digital input line 7 can stop the A/D operation on
subsystem 3.
c. The filter is either 0 Hz or 100 Hz.
d. The A/D ranges are 0 to 2.5 V,
−
0.10 to 2.5 V, and ±2.5 V.
e. The D/A range is ±5 V.
f. The A/D resolution is 24 bits.
g. The D/A resolution is 16 bits.
