Name Reference Direction Description
PACER
_OUT DGND Output
Pacer Clock Output - This pin pulses once for
each pacer clock when turned on. If A/D
conversion is in the pacer trigger mode, users
can use this signal as a synchronous signal for
other applications. A low-to-high edge triggers
A/D conversion to start.
TRG _GATE D GND Input
A/D External Trig g er Gate - This pin is
external trigger signal input gate control. When
TRG _GATE is connected to +5 V, it will enable
the external trigger signal to input. When TRG
_GATE is connected to D GND, it will disa b le
the external trigger signal to input.
EXT _TRG D GND Input
A/D External Trig g er - This pin is external
trigger signal input for the A/D conversion. A
low-to-high edge triggers A/D conversion to
start.
+12V DGND Output +12 VDC Source - This pin is +12V power
supply.
+5V DGND Output +5 VDC Source - This pin is +5 V power
supply.
