Theory of Operation for SDM-USB-DIG Platform
The SDM-USB-DIG platform is a general-purpose data acquisition system that is used on select TI EVMs.
The core component of the platform is the MSP430F5528, an ultra-low power 16-bit MCU. The
microcontroller receives information from the host PC and translates it into I2C, SPI, or other digital I/O
patterns. The connected device (in this case, the AMC7832 device) connects to the I/O interface of the
platform. During digital I/O transactions, the platform obtains information from the AMC7832 device and
sends to the host PC for interpretation. A block diagram of the platform is shown in Figure 3.

AMC7832EVM ADC Page
This page provides insight into the functionality of the AMC7832 device’s (17) channel 12-bit ADC. The
ADC block includes 12 high-voltage bipolar ADC channels featuring a –12.5-V to 12.5-V input range, and
5 low-voltage unipolar analog channels that accept a range of 0-V to 5-V. The high-voltage channels are
labeled as (ADC0 through ADC11), while the low-voltage channels are printed as (LV_ADC12 through
LV_ADC16). Figure 12 displays the ADC Page.
Figure 12. ADC Page
To completely activate the ADC block, the Enable Reference Block must be enabled, along with the
Enable Internal Reference Buffer and Power ADC Block. This sequence is shown in Figure 13.

After the device is configured, individual channels can be enabled by selecting their respective ADC MUX
button, as shown in Figure 14.
Figure 14. ADC Channel MUX
To trigger conversions, press the Start Conv button or automatically trigger conversions before every read
by enabling the auto-trigger checkbox. The ADC data registers, displayed on the right side of the GUI, are
updated with the converted results when the Read ADC button is pressed.
Most of the controls listed within the ADC image are used to setup the ADC configuration register. These
include the conversion rate and conversion mode parameters, which are selectable through their
respective drop-down list. The selectable conversion rates are listed in Table 10.

The conversion mode can be either auto or direct mode. In direct mode, the analog inputs, specified in the
ADC channel registers, are converted sequentially one time. In auto mode, the analog inputs are
converted sequentially and repeatedly. After a conversion is completed, the ADC multiplexer returns to the
first channel and repeats the process.
The internal local temperature sensor is accessible through the LT Sensor button and is updated after a
conversion is triggered and the Read ADC button is pressed.
5.2.4
AMC7832EVM DAC Page
The DAC page gives the user an interface to observe and control the different data registers, modes, and
configurations available for each individual DAC channel.
To fully activate the DAC block, set the Enable Reference Block. To set the DAC channels individually,
select their respective checkbox in the Power DACs column (see Figure 15).

Figure 15. DAC Page
The 12 DAC channels are broken up into different DAC banks, where each channel within a bank shares
a common programmable voltage range, which is selectable through the Program Range column. The
default range upon startup is the 0-V to 10-V range, but it should be noted that this range is not fully
realizable because AVCC is connected to the +5-V LDO supply. For default operation, it is better to select
the 0-V to 5-V range. If the 0-V to 10-V range is desired, populate the correct shunt resistor for AVCC,
shown in Table 5, to connect the AVCC supply to +12-V.
NOTE: Special care must be taken when selecting the –10-V to 0-V range, as this requires an
external jumper modification and also requires that the user select the appropriate Output
Reference button. The Output Reference 1 button sets the negative voltage range for DAC
Banks A and B, while the Output Reference 2 button sets the negative range for DAC Banks
C and D. The DAC voltage range jumper settings are displayed in Table 8. Ensure that the
AMC7832EVM board is powered off before selecting different jumper positions.
The DAC page also displays two input fields in the Program Values column (see Figure 16).

Either one of these windows can be programmed with the desired DAC output voltage or hexadecimal
value. When these values are entered, they are instantly written to the internal DAC buffer register.
Pressing the Register Update button shifts the contents of the DAC buffer stage to the DAC latch stage,
which then updates the DAC output voltage.
The Read Back column allows the user to read back the register contents of either the latch or buffer
stage, which is selectable through the Boolean checkbox below the Read DACs button, as shown in
Figure 17. The results are read back after the Read DACs button is pressed.

AMC7832EVM ALARMS Page
The AMC7832 ALARMS page gives the user access to the programmable out-of-range alarms for the
internal temperature sensor and low-voltage ADC channels (ADC12 through ADC16). Figure 18 displays
the ALARMS page of the AMC7832EVM. The page displays the name of each alarm, shown in the Alarm
Name column, and provides information such as the value, high limit, low limit, and alarm status, along
with other additional options.
Figure 18. ALARMS Page
To use the ALARMS page, enable the ADC channel or temperature sensor in the ADCs page of the GUI.
Achieve this by enabling the appropriate channel’s mux. After the channels are active, the Low Limit and
High Limit fields are available to edit (see Figure 19).

Figure 19. Enable Low Limit and High Limit Fields
The Write Settings button is used to write the values from the Low Limit and High Limit fields into the
device. The Read Alarm button is used to read the state of the active channels. When an alarm is
triggered, the Alarm Status will display the text ‘Tripped’ in red. If the channel values are within the range
of the alarm thresholds the status will display ‘No Alarm’ in black text.
Figure 20 displays the False Alarm protection, CH-FALR-CT drop-down list, which contains integer values
that are related to the consecutive number of samples required for the alarm to activate. The list defaults
to 16 consecutive samples, and therefore requires 16 conversions with an over range value before the
alarm is triggered.
Figure 20. CH-FALR-CT Menu
The CLR, ALARM OUT, and DACs to CLR column, as shown in Figure 21, allow the user to tie DAC
output behavior to alarm events. By selecting the CLR checkbox, the alarm events are able to force the
DACs into a clear state, regardless of which DAC operation mode is active, auto or manual. The DAC
channels to clear are selectable under the DACs to CLR column.
Figure 21. Clear DAC Options
The ALARM OUT checkbox allows the device to create an external signal on GPIO1 that goes low (active)
when an alarm event is detected. The general-purpose I/O, more specifically GPIO1 must be configured
for ALARMOUT for this function to take effect.
The ALARMIN-ALR checkbox gives the user the ability to clear the DACs with an active low input signal
through GPIO0. Just as with GPIO1, GPIO0 must be configured for ALARMIN for this function to take
effect.

The ALARMIN-ALR-OUT checkbox enables the propagation of alarm signals by allowing the user to input
an active-low signal to the ALARMIN pin, which then creates an active low signal on the ALARMOUT pin.
These functions need to be set in the GPIO configuration register, which is available for configuration in
the GPIO page of the AMC7832EVM GUI.
5.2.6
AMC7832EVM GPIO Page
The AMC7832 GPIO page features the first four (GPIO0 to GPIO3) general-purpose I/O of the AMC7832
device. These four GPIOs are also configurable for other specific functions, including the ability to
externally trigger conversions, enable alarms, and provide an output indicating conversion completion. The
GPIO page also provides a detailed description textbox that gives more information about the different
GPIO pins as the user hovers over the pulldown list under the GPIO Block column (see Figure 22).
Figure 22. GPIO Page
Use the GPIO Block section of the GPIO tab, as shown in Figure 23, to set the various GPIO functions.
The drop-down menu defaults to general-purpose I/O. To perform a write or read, set the W/R Function
pulldown to either Write or Read. The W/R value enables the user to input or observe the Boolean value
of the GPIO register. Press the Generate Write/Read button to write to or read from the GPIO pin.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
