DEMO MANUAL DC934A

Quick start proceDure

Connect DC934A 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

evaluation software supplied with DC590 or download it

from www.linear.com/software. The correct control panel

will be loaded automatically. Click the COLLECT button to

begin outputting codes to the DAC and reading back the

resulting output voltage.

Complete software documentation is available from the

Help menu item, as features may be added periodically.

HarDware setup

JUMPERS

JP1: VREF Select. Select 5V, 4.096V, or 2.5V reference.

To apply an external reference through the VREF turret,

remove this jumper.

JP2: VCC Select. VCC is taken either from the onboard 5V

reference or the 5V regulated supply from the controller

board. Selecting the 5V reference for VCC and VREF allows

characterization of rail to rail operation of the LTC2607.

JP3: ADC Disable. Set to ON for operation with DC590 se-

rial controller. When using in customer’s end application,

the ADC can be completely disabled by setting jumper to

DISABLE.

For very sensitive noise measurements when using LTC

supplied software, set the output voltage and stop reading

voltage via the collect button on the control panel.

JP5: REFLO connection – either grounded or externally

supplied.RefertotheLTC2607datasheetforREFLOdetails.
