Connections: Channel 1, 2, and 3
Each DAC channel makes two connections to the
425: 0 to +10V output, and output return.
Connector Pinout
All external circuitry connects to the DAC channels
through 40-pin header P2. Connector P2 is shared by
the D/A and A/D converter circuits.
This table shows the portion of connector P2 used by
DAC channels:

Connections: Channel 0
In addition to output and return, channel 0 has a
connection for remote voltage sensing. The remote
sense signal must be connected to the output signal.
Connect the output and sense signals near to the load
for best accuracy.

Connections: Channel 0 with External Buffer
In applications that use an external buffer for DAC
channel 0, it is best to sense the voltage at the buffer
output instead of the DAC output.
