ABSTRACT
The ADS1x15V2EVM-PDK is comprised of the ADS1x15 evaluation module (EVM) and the PAMBoard
motherboard. The combination of the ADS1x15EVM and PAMBoard allows users to evaluate the functionality
of the Texas Instruments' 16-bit ADS1115 or the 12-bit ADS1015. ADS1x15 refers to what is common to
both devices and EVMs. Any differences in operation between the devices or EVMs is listed separately. The
ADS1x15 devices are ultra-small, low-power, analog-to-digital converters (ADCs) with an integrated comparator.
Each ADS1x15 device has inputs that can be configured as four single-ended or two differential inputs. This
document describes both the EVM hardware platform and the graphical user interface (GUI) software used to
configure and operate the device. The user’s guide also includes the EVM schematic diagram, board layout, and
bill of materials. The EVM platform eases the evaluation of the ADS1x15 device with hardware, software, and
computer connectivity through the universal serial bus (USB) interface.

1 Introduction
The ADS1x15V2EVM-PDK is a fully assembled evaluation platform designed to highlight the ADS1x15 features
and modes of operation that make this device suitable for low-power applications. The ADS1x15EVM sits on
top of an accompanying precision ADC motherboard (PAMBoard) used as a USB-to-PC GUI communication
bridge. The board combination also serves as an example implementation of connecting a microcontroller (MCU)
to communicate with the ADS1x15 device through an inter-integrated circuit (I2C) interface. Figure 1-1 shows a
block diagram of the ADS1x15V2EVM-PDK.
Note
The ADS1x15EVM requires an external controller to evaluate the ADS1x15 device.
The PAMBoard is controlled by commands received from the ADS1x15V2EVM-PDK GUI, and returns data to
the GUI for display and analysis. If the PAMBoard is not used, the EVM plug-in module format allows for an
alternative external host to communicate with the ADS1x15 by connection through the pin headers J1 through
J4. Connections to the header are identified on the PCB silkscreen and listed in Table 3-1.
The combined ADS1x15EVM and PAMBoard make up the ADS1x15V2EVM-PDK and incorporates the following
features:
• ADS1x15, four input-channel ADC with header or screw terminal block input connections
• Voltage selection of 3.3-V or 5-V operation for the ADS1x15 with level-shifting to the 3.3-V MCU
• Full-scale ranges from 256 mV to 6.144 V
• I2C for communication and configuration

2 Quick Start
The quick start shows a minimalist startup process to get the GUI working with the EVM and to see a simple
example for data collection. Details on each step are described in this document. Specifics regarding the GUI
installation steps are found in Section 4.2.
2.1 Step 1 - Hardware Setup
The EVM hardware configuration consists of verifying the supply settings and adding a source voltage to be
converted. Figure 2-1 shows the EVM hardware setup.
1. Verify that the ADS1x15 supply voltage is set to the 5-V setting at JP1.
2. Connect an input voltage to AIN0. The PAMBoard supply voltage can be used as a voltage source to the
ADS1x15. Use the 3.3-V source found at header J1 pin 1 and with a wire jumper connected to the J6 header
at pin 1 (A0).

3 ADS1x15EVM Overview
Various onboard components are used to interface the analog input, digital interface, and provide power to the
ADS1x15 device. The functional block diagram shows an ADS1x15V2EVM-PDK board overview.
3.1 ADS1x15EVM-to-PAMBoard Interface
The ADS1x15EVM supports the digital I2C and functional modes as detailed in the ADS1115 data sheet (or the
ADS1015 data sheet). The PAMBoard operates at a 3.3-V logic level and the digital I/O lines of the ADC are
level shifted to match the operating voltage of the ADS1x15.
Digital interface connections to the PAMBoard include power, I2C, and a GPIO connection used for triggering an
alert at the end of conversion if enabled. The digital connections are highlighted in the silkscreen, as shown in
Figure 3-1. Details regarding the connections are shown in Table 3-1.

3.2 Digital Interface
As noted in Section 3.1, the ADS1x15 interfaces with the PAMBoard and the PAMBoard communicates with
the computer over USB. The two devices on the EVM requiring communication are the ADS1x15 ADC (U1)
and the electrically erasable programmable read-only memory (EEPROM) (U3) using I2C (see Figure 6-5). The
EEPROM is preprogrammed with the information required to configure and initialize the ADS1x15V2EVM-PDK
GUI software platform. When the hardware is initialized through the software, the EEPROM is no longer used.
The PAMBoard and EEPROM (U3) use 3.3 V for the device interface logic levels. The ADS1x15 can operate at
either 3.3 V or 5 V as desired by jumper selection JP1. To allow the ADS1x15 to operate at 5-V logic levels, a
logic level translator (U2) is used.
3.3 Analog Input Connections
The ADS1x15 device is designed for easy interface to an external sensor that is differential or single-ended
using either a header (J6) or a screw terminal block (J5). Connector J6 provides an easy interface connection for
differential input pairs with each pair separated by analog ground. Table 3-2 lists the channel input connections
for J5 and Table 3-3 shows the input connections for J6. Both connectors are clearly labeled on the PCB
silkscreen for easy input connection identification.

Connector J5 is a screw terminal block for attaching an external sensor with bare wire connections. The terminal
block includes all four inputs and a connection point for analog ground. Figure 3-2 shows the input layout.
Figure 3-2. Analog Input Terminal Block (J5)
Connector J6 is a 100-mil spaced dual-row header. Jumper wire or clip leads can be used for connections. The
header includes all four inputs and two analog ground connections. Figure 3-3 shows the input layout.

Each analog input includes a single-order, low-pass filter. The single-ended input filter cutoff frequency is
67.9 kHz. Up to four separate single-ended measurements are possible.
Instead of single-ended measurements, up to two differential input pair combinations are possible. The filter
design for the differential input pair filtering has a cutoff frequency of 3.4 kHz. The filter is populated on the
ADS1x15EVM for input pair combinations of AIN0 and AIN1 or AIN2 and AIN3. The input combination of AIN1
and AIN2 is possible by adding a 47-nF capacitor at C6 (see location in Figure 6-5).
CAUTION
The configuration options for the ADS1x15 allow for a potential full-scale range (FSR) greater than
the supply. This increased range is useful when an input voltage slightly exceeds the next lower
FSR. However, the input voltage should not exceed the range of the VDD supply selected at JP1.
The absolute input voltage is bounded by VDD + 0.3 V and GND – 0.3 V. Damage to the ADS1x15
may occur if the absolute input range is exceeded.

3.4 Power-Supply Options
The ADS1x15 supports a wide range of supply voltage from 2 V to 5.5 V. The ADS1x15EVM ADC voltage (VDD)
can operate from either 3.3 V or 5 V. Power is supplied from the USB 5-V source to the PAMBoard. However,
the USB power-supply voltage is not consistent from PC to PC. A DC/DC converter increases the USB output
to 5.5 V. A linear low dropout (LDO) regulator uses 5.5 V to establish a clean and stable 5 V and 3.3 V for the
ADS1x15V2EVM-PDK.
When the USB cable is plugged into the PC, two LEDs will light on the PAMBoard (Figure 3-4). The bottom LED
(D5) indicates that the 5-V output is active. The top LED (D1) indicates that the ADS1x15V2EVM-PDK is ready
to communicate with the GUI.
Figure 3-4. LED Indicators D1 and D5
Jumper JP1 selects the operating voltage for the ADS1x15 (Figure 3-5). When jumper JP1 is in the bottom
position the VDD to the ADS1x15 is set to 5 V and when in the top position the VDD supply is set to 3.3 V.
