5.9.1.1 Amplifier Bypass Mode Conversion Timing
MC68F375
REFERENCE MANUAL
If the amplifier bypass mode is enabled for a conversion by setting the amplifier bypass
(BYP) bit in the CCW, the timing changes to that shown in
sample time is eliminated, reducing the potential conversion time by two QCLKs. How-
ever, due to internal RC effects, a minimum final sample time of four QCLKs must be
allowed. This results in no savings of QCLKs. When using the bypass mode, the exter-
nal circuit should be of low source impedance, typically less than 10 k . Also, the
loading effects of the external circuitry by the QADC64 need to be considered, since
the benefits of the sample amplifier are not present.
QCLK
QCLK
Because of internal RC time constants, a sample time of 2 QCKLs in
bypass mode for high frequency operation is not recommended.
