Hi,
I have a few questions about the calibration of the ADC12D1600QML.
After the application of power, and PDI and PDQ are deasserted, does the device automatically enter a calibration cycle? Is another calibration cycle necessary and, if so, is there any requirement to wait a certain time after power and the clock signal is applied?
In the board design that I'm working with, the inputs are DC coupled and are driven by a single-ended to differential amplifier. This amplifier is powered down when I initiate a calibration cycle. At that point, the inputs to the ADC are 0 volts. Is that OK? Should I recalibrate after the amplifier is powered up? The design is such that the TI ADC is powered on prior to the amplifier, and the amplifier is powered off before the TI ADC is powered off.
Thanks,
Rich :-)
