Part Number: TMDSCNCD28388D
TMDSCNCD28388D control card have three DACs of 12 bit resolution from 0 to 4095 counts for voltage range of 0 to 3.3 voltage. Tested DAC output on TMDSCNCD28388D control card , uploaded example program of buffdac_ex1_enable in DSC, connected a jumper wire from 3V3 (3.3 volt) to pin No.12 of docking station (ADCINB0) for DAC reference. Voltage between pin No.9 & GND (3V3 GND) on Dock station measured a voltage of 1.6volt for counts of 2048 and similarly between pin No.9 & GND (3V3 GND) on Dock station measured a voltage of 0.8volt for counts of 1024. this is unipolar DAC output from 0 to 3.3 volt.
1).Please suggest how to generate Bipolar DAC output from -1.65 Volt to +1.65 volt for counts of 0 to 4095.
2).When I measure Voltage between pin No.9 and Pin No.13 (GND), nothing is generating. please explain the issue.
