1 Introduction
The ADS7142-Q1 BoosterPack™ is a fully-assembled evaluation platform designed to highlight the ADS7142-Q1
features and various modes of operations that makes this device suitable for ultra-low-power, small-size sensor
monitor applications.
The accompanying Precision ADC Motherboard (PAMB) development kit is used as a USB-to-PC GUI
communication bridge, and example implementation of a master MCU to communicate with the ADS7142-Q1
through its I2C interface.
Note
The BOOSTXL-ADS7142-Q1 requires an external master controller to evaluate the ADS7142-Q1.
The PAMB is controlled by commands received from the ADS7142-Q1 GUI, and returns data to the GUI
for display and analysis. If the PAMB is not used, the BoosterPack™ plug-in module format of the BOOSTXL-
ADS7142-Q1 board allows an alternative external host to communicate with the ADS7142-Q1.
The BOOSTXL-ADS7142-Q1 incorporates all required circuitry and components with the following features:
• ADS7142-Q1 nano power, ultra-small, dual-channel sensor monitor with I2C interface and alert output
• Optional low power voltage reference, TI’s REF3133-Q1, to generate a 3.3-V output to power the ADS7142-
Q1 AVDD supply pin when the 5-V USB power from the PAMB
• Optional adjustable linear regulator, TI’s TPS79933-Q1, to generate stable output voltage to power the
ADS7142-Q1 DVDD pin when using the 5-V USB power from the PAMB
• I2C interface for communication and configuration of modes available on the ADS7142-Q1

2.2 Digital Interface
As noted in Section 1, the BOOSTXL-ADS7142-Q1 interfaces with the PAMB, which in turn communicates with
the computer over USB. The two devices on the booster pack that the PAMB communicates over I2C are the
ADS7142-Q1 ADC and the EEPROM. The EEPROM comes preprogrammed with the information required to
configure and initialize the BOOSTXL-ADS7142-Q1 platform. Once the hardware is initialized, the EEPROM is
no longer used.
2.3 ADS7142-Q1 Digital I/O Interface
The BOOSTXL-ADS7142-Q1 supports the I2C digital interface and functional modes as detailed in the
ADS7142-Q1 data sheet. The PAMB is capable of operating at a 3.3 V logic level and is directly connected
to the digital I/O lines of the ADC.
2.4 Power Supplies
The device supports a wide range of operation on its analog supplies. The AVDD can operate from 1.65 V to
3.6 V. The DVDD operates from 1.65 V to 3.6 V, independent of the AVDD supply. The 3.3 V voltage regulator
available on the PAMB is used to supply 3.3 V to both AVDD and DVDD on the BOOSTXL-ADS7142-Q1.
There is an onboard option to use an ultra-low power voltage reference REF3133-Q1 (U2) to generate 3.3 V
supply for the ADS7142-Q1 AVDD pin. Voltage variants of REF3330 can be used to generate supply other than
3.3 V for the ADS7142-Q1 AVDD pin. To generate a DVDD supply other than 3.3 V, an adjustable version of the
TPS799-Q1 regulator (U3) can be used.

4 ADS7142-Q1 GUI Functional Modes
The ADS7142-Q1 device has the following functional modes:
•Manual Mode: In this mode, the host provides I2C frames to control conversion and read data after each
conversion.
•Autonomous Mode: The device features an internal data buffer that can store the conversion results of the
ADC in Autonomous Mode without the host controlling the conversion.
•High Precision Mode: In High Precision Mode, the results stored in the internal data buffer are accumulated
to increase the precision of the conversion results.
The device powers up in Manual Mode and can be configured into any of the functional modes by writing the
configuration registers for the desired mode.
4.1 Autonomous Mode
In the Autonomous Conversion Mode, the device generates the start of conversion pulses using an internal
oscillator on receiving the first start of conversion pulse from the host. This can be configured by selecting
Autonomous Mode as the Conversion Mode, selecting one of the Operating Modes from the drop-down menu,
and pressing the SET button. The ADS7142-Q1 device then generates the subsequent start of conversion
signals autonomously. The Operating Modes offered in Autonomous Mode are described in the following
sections.
4.1.1 Start Burst Mode
When Start Bust Mode is selected from the Operating Modes drop-down menu and the SET button is pressed,
the device is configured to store 16 conversion results into the data buffer of the device. The device will stop
converting once the data buffer is filled. To understand the steps required to configure the device in this mode,
refer to the ADS7142-Q1 data sheet.
Figure 4-1 highlights the ADS7142-Q1 GUI working in Start Burst Mode.

4.1.3 Pre Alert Mode
When Pre Alert Mode is selected from the Operating Modes drop-down menu and the SET button is pressed,
the device starts conversions and stores the data in the data buffer until the input signal crosses either the high
or low threshold for the channels selected in the sequence. If the user aborts the sequence before the data
buffer is filled, the device will abort the sequence and stop storing the conversion results. To understand the
steps required to configure the device in this mode, refer to the ADS7142-Q1 data sheet.
Figure 4-3 shows the ADS7142-Q1 GUI configured in Pre Alert Mode with the Alert functionality enabled on
channel 0. In this example, the High Threshold, Hysteresis, and Low Threshold are set. The thresholds are
marked on the graph in pink and hysteresis is indicated by the dotted line.

4.1.4 Post Alert Mode
When the device is configured in Post Alert Mode operation, the device starts converting the input signal and
storing the data in the data buffer only after it reaches one of the Alert thresholds set for the channels selected
in the sequence. If the user aborts the sequence before the data buffer is filled, the device stops storing
the conversion results. To understand the steps required to configure the device in this mode, refer to the
ADS7142-Q1 data sheet.
Figure 4-5 highlights the ADS7142-Q1 GUI working in Post Alert Mode. Once either of the low or high thresholds
is reached, make sure to read the Alert by clicking on the highlighted Alert block in red before running the next
sequence.

4.2 High Precision Mode
The High Precision Mode increases the accuracy of the data measurement to 16-bit accuracy. This is useful
for applications where the level of precision required to accurately measure the sensor output needs to be
higher than 12-bits. When High Precision Mode is selected from the Operating Modes drop-down menu and
the SET button is pressed, the device starts conversions and starts accumulating the conversion results in an
accumulator. The device stops accumulating the conversion results in the accumulator after 16 conversions. If
the user aborts the sequence before 16 conversions, then the device will abort the sequence. To understand the
steps required to configure the device in this mode, refer to the ADS7142-Q1 data sheet.
Figure 4-6 highlights the ADS7142-Q1 GUI working in High Precision Mode. The maximum number of
accumulator count that can be entered into the ACCUMULATOR_CFG register is 15 (0x0F) which corresponds
to 16 conversions.

4.3 Manual Mode
Manual Mode allows the external host processor to directly request and control when the data is sampled. The
data capture is initiated by an I2C command from the host processor and the captured data is then returned over
the I2C bus. Manual Mode can work one of the following states based on power up or user-initiated conditions.
4.3.1 Default Mode
On power up, the device is in Manual Mode with single-ended and dual-channel configuration and it samples
the analog input applied on Channel 0 (AIN0-GND). In this mode, the device uses high-frequency oscillator for
conversions. Figure 4-7 highlights the ADS7142-Q1 GUI working in Manual Mode: Default State.
