DESCRIPTION
NO.
DAC[A:D]
Reference voltage input (0.5 V). When the DAC is not used, the DAC_VREF signal
should be connected to V
SS
.
Output of DAC A. When the DAC is not used, the DAC_IOUT_A signal should be
left as a No Connect.
Output of DAC B. When the DAC is not used, the DAC_IOUT_B signal should be
left as a No Connect.
Output of DAC C. When the DAC is not used, the DAC_IOUT_C signal should be
left as a No Connect.
Output of DAC D. When the DAC is not used, the DAC_IOUT_D signal should be
left as a No Connect.
1.8-V analog I/O power. When the DAC is not used, the V
DDA_1P8V
signal should be
connected to V
SS
.
Analog I/O ground. When the DAC is not used, the V
SSA_1P8V
signal should be
connected to V
SS
.
1.20-V analog core supply voltage (-594 device). When the DAC is not used, the
V
DDA_1P1V
signal should be connected to V
SS
.
Analog core ground. When the DAC is not used, the V
SSA_1P1V
signal should be
connected to V
SS
.
External resistor connection for current bias configuration. This pin must be
connected via a 4-k
resistor to V
. When the DAC is not used, the
DAC_RBIAS signal should be connected to V
SS
.
