A simplified functional block diagram of the ADC module is shown in
Figure 4-7
. The ADC module
consists of a 12-bit ADC with a built-in sample-and-hold (S/H) circuit. Functions of the ADC module
include:
12-bit ADC core with built-in S/H
Analog input: 0.0 V to 3.0 V (Voltages above 3.0 V produce full-scale conversion results.)
Fast conversion rate: 160 ns at 12.5-MHz ADC clock, 6.25 MSPS
16-channel, MUXed inputs
Autosequencing capability provides up to 16 "autoconversions" in a single session. Each conversion
can be programmed to select any 1 of 16 input channels
Sequencer can be operated as two independent 8-state sequencers or as one large 16-state
sequencer (i.e., two cascaded 8-state sequencers)
Sixteen result registers (individually addressable) to store conversion values
The digital value of the input analog voltage is derived by:
A.
All fractional values are truncated.
Multiple triggers as sources for the start-of-conversion (SOC) sequence
S/W - software immediate start
ePWM start of conversion
XINT2 ADC start of conversion
Flexible interrupt control allows interrupt request on every end-of-sequence (EOS) or every other EOS.
Sequencer can operate in "start/stop" mode, allowing multiple "time-sequenced triggers" to
synchronize conversions.
SOCA and SOCB triggers can operate independently in dual-sequencer mode.
Sample-and-hold (S/H) acquisition time window has separate prescale control.
The ADC module in the 280x has been enhanced to provide flexible interface to ePWM peripherals. The
ADC interface is built around a fast, 12-bit ADC module with a fast conversion rate of 160 ns at 12.5-MHz
ADC clock. The ADC module has 16 channels, configurable as two independent 8-channel modules. The
two independent 8-channel modules can be cascaded to form a 16-channel module. Although there are
multiple input channels and two sequencers, there is only one converter in the ADC module.
Figure 4-7
shows the block diagram of the ADC module.
The two 8-channel modules have the capability to autosequence a series of conversions, each module
has the choice of selecting any one of the respective eight channels available through an analog MUX. In
the cascaded mode, the autosequencer functions as a single 16-channel sequencer. On each sequencer,
once the conversion is complete, the selected channel value is stored in its respective RESULT register.
Autosequencing allows the system to convert the same channel multiple times, allowing the user to
perform oversampling algorithms. This gives increased resolution over traditional single-sampled conver-
sion results.
