Connections: Channel 1, 2, and 3

Each DAC channel makes two connections to the

421: 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.

The table below defines that portion of connector P2

used for the 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.
