DEMO MANUAL DC1488A
QUICK START PROCEDURE
HARDWARE SETUP
Connect DC1488A to a DC590 USB serial controller using
the supplied 14 conductor ribbon cable. Connect DC590 to
a host PC with a standard USB A/B cable. Run the evalu-
ation software supplied with DC590 or download it from
www.linear.com. The correct control panel will be loaded
automatically. To update DAC values, enter new value in
corresponding output text box and press enter. Be sure
the DAC is enabled.
Complete software documentation is available from the
Help menu item, as features may be added periodically.
Analog Connections
DAC Outputs: The four DAC outputs from the LTC2634
are brought out to turrets labeled V
OUTA
through V
OUTD
.
These may be connected to external instruments or other
circuitry.
NOTE: DAC outputs are not in alphabetical order on the
circuit board.
VREF: The REF turret is connected directly to the reference
terminals of the LTC2634. When the integrated reference
is being used, the reference voltage may be monitored at
this point. An external reference may also be applied to this
turret after changing the setting in the QuikEval™ software.
Grounding And Power Connections
Power (VCC): Normally DC1488A is powered by the DC590
controller. VCC can be supplied to this turret, however the
power supply on DC590 must be disabled! Refer to the
DC590 Quick Start Guide for more details on this mode
of operation.
Grounding: Ground turrets as well as 2 grounding strips
are provided.
