The queued analog-to-digital converter (QADC) is a 10-bit, unipolar,
successive approximation converter. Up to eight analog input channels
can be supported using internal multiplexing. A maximum of 18 input
channels can be supported in the expanded, externally multiplexed
mode.
The QADC consists of an analog front-end and a digital control
subsystem, which includes an IPbus interface block.
