22.2
This ADC module is designed for applications that
require low latency between the request for conversion
and the resultant output data. Typical applications
include:
• AC/DC power supplies
• DC/DC converters
• Power Factor Correction (PFC)
This ADC works with the high-speed PWM module in
power control applications that require high-frequency
control loops. This module can sample and convert two
analog inputs in a 0.5 microsecond when two SARs are
used. This small conversion delay reduces the “phase
lag” between measurement and control system
response.
Up to five inputs may be sampled at a time (four inputs
from the dedicated sample and hold circuits and one
from the shared sample and hold circuit). If multiple
inputs request conversion, the ADC will convert them in
a sequential manner, starting with the lowest order
input.
This ADC design provides each pair of analog inputs
(AN1,AN0), (AN3,AN2),..., the ability to specify its own
trigger source out of a maximum of sixteen different
trigger sources. This capability allows this ADC to
sample and convert analog inputs that are associated
with PWM generators operating on independent time
bases.
The user application typically requires synchronization
between analog data sampling and PWM output to the
application circuit. The very high-speed operation of
this ADC module allows “data on demand”.
In addition, several hardware features have been
added to the peripheral interface to improve real-time
performance in a typical DSP-based application.
• Result alignment options
• Automated sampling
• External conversion start control
• Two internal inputs to monitor 1.2V internal
