Queued Analog-to-Digital Converter (QADC)

Technical Data

The QADC requires accurate, noise-free input signals for proper
operation. This section discusses the design of external circuitry to
maximize QADC performance.
No A/D converter can be more accurate than its analog reference. Any
noise in the reference can result in at least that much error in a
conversion. The reference for the QADC, supplied by pins V
should be low-pass filtered from its source to obtain a noise-free, clean
signal. In many cases, simple capacitive bypassing may suffice. In
extreme cases, inductors or ferrite beads may be necessary if noise or
RF energy is present. Series resistance is not advisable since there is
an effective dc current requirement from the reference voltage by the
internal resistor string in the RC DAC array. External resistance may
introduce error in this architecture under certain conditions. Any series
devices in the filter network should contain a minimum amount of DC
resistance.
For accurate conversion results, the analog reference voltages must be
within the limits defined by V
subsection.
