Technical Data

NOTE:
If the amplifier bypass mode is enabled for a conversion by setting the
amplifier bypass (BYP) field in the CCW, the timing changes to that
shown in

eliminated, reducing the potential conversion time by two QCLKs. When
using the bypass mode, the external circuit should be of low source
impedance (typically less than 10 k ). Also, the loading effects to the
external circuitry by the QADC need to be considered, since the benefits
of the sample amplifier are not present.
Because of internal RC time constants, it is not recommended to use a
sample time of two QCLKs in bypass mode for high-frequency operation.
The internal multiplexer selects one of the eight analog input pins for
conversion. The selected input is connected to the Sample Buffer
Amplifier or to the sample capacitor. The multiplexer also includes
positive and negative stress protection circuitry, which prevents
deselected channels from affecting the selected channel when current is
injected into the deselected channels.
The sample buffer is used to raise the effective input impedance of the
A/D converter, so that external components (higher bandwidth or higher
impedance) are less critical to accuracy. The input voltage is buffered
onto the sample capacitor to reduce crosstalk between channels.
