What is the settling time value for AD9363 auxiliary DAC's - B3 and C3 pins?
When the DAC output changes from minimum output (0.5V) to maximum output (3V).
In certain applications, it is desirable to delay the AuxDAC transition after the enable signal transitions. Each AuxDAC has its own receive and transmit mode delay setting in Register 0x30 through Register 0x33. Each LSB equals approximately 1 μs. Register 0x3A must be set based on your reference clock to program a 1 μs delay. Set Bits[D6:D0] to the number of reference clock cycles per μs minus one. Figure 55 shows the AuxDAC code vs. output voltage for four different reference voltage settings for AuxDAC 1.
