ADS1x15V2EVM-PDK User's Guide
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
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.

Page 4: Introduction
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. -

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. - Page 10 The absolute input voltage is bounded by VDD + 0.3 V and GND – 0.3 V.
