Texas Instruments ADS1115V2EVM-PDK

Overview

ADS1115V2EVM-PDK from Texas Instruments is a fully assembled evaluation platform combining the ADS1115 16-bit delta-sigma ADC evaluation module and the PAMBoard motherboard to enable USB-connected, GUI-driven characterization of analog input configurations, full-scale range selection (±256 mV to ±6.144 V), I²C register control, and real-time data capture with FFT and histogram analysis - used for sensor interface validation in industrial monitoring and low-power embedded systems.

For engineers reviewing the ADS1115V2EVM-PDK datasheet, ADS1115V2EVM-PDK pinout, ADS1115V2EVM-PDK application, or ADS1115V2EVM-PDK equivalent, this page delivers verified hardware interface details, supported supply voltages (3.3 V or 5 V), analog input options (screw terminal J5 or header J6), I²C communication path via level-shifting logic, and GUI-based configuration workflow for rapid ADC evaluation without custom firmware development.

Technical Context

The ADS1115V2EVM-PDK implements a two-board architecture: the ADS1115EVM hosts the ADS1115 ADC (U1), level-shifter (U2), EEPROM (U3), and analog RC filters; the PAMBoard provides USB-CDC/Bulk interface, 3.3-V/5-V LDO regulation, and GPIO-triggered ALERT/RDY signaling. Communication occurs over I²C at standard-mode (100 kHz) or fast-mode (400 kHz) speeds, with EEPROM preprogrammed for GUI initialization.

Analog inputs support four single-ended channels (AIN0–AIN3) or two differential pairs (AIN0–AIN1, AIN2–AIN3), each with dedicated RC filtering - 67.9 kHz cutoff for single-ended, 3.4 kHz for differential. Input voltage range is bounded by VDD + 0.3 V and GND – 0.3 V, with JP1 jumper selecting either 3.3-V or 5-V VDD operation.

FAQ

What is the primary function of the ADS1115V2EVM-PDK?

The ADS1115V2EVM-PDK is an evaluation platform consisting of the ADS1115 16-bit delta-sigma ADC module and the PAMBoard motherboard. Its primary function is to provide a complete, USB-connected system for configuring, capturing, and analyzing analog input signals using the ADS1115 device - including real-time FFT, histogram, and register-level control via a web-based GUI. The ADS1115V2EVM-PDK enables rapid validation of sensor interfaces without custom hardware or firmware.

Does the ADS1115V2EVM-PDK require external programming or drivers?

No external programming is required for basic operation. The ADS1115V2EVM-PDK enumerates as a USB CDC/Bulk composite device; drivers install automatically on Windows/macOS/Linux. First-time use requires installing the TI Cloud Agent and browser extension (for Chrome or Firefox), after which the web-based GUI connects directly. Firmware updates for the PAMBoard are optional and only needed if TI releases new functionality - the ADS1115V2EVM-PDK ships with fully functional factory firmware.

How are analog inputs connected to the ADS1115V2EVM-PDK?

Analog inputs connect via two onboard interfaces: J5 (4-position screw terminal block) accepts bare-wire connections for AIN0–AIN3 and AGND; J6 (100-mil dual-row header) supports jumper wires or clip leads for the same channels plus two AGND pins. Both connectors are silkscreen-labeled and documented in Table 3-2 and Table 3-3 of the ADS1115V2EVM-PDK User's Guide. RC filters are populated per channel - 67.9 kHz for single-ended, 3.4 kHz for differential pairs.

Can the ADS1115V2EVM-PDK operate with a microcontroller instead of the PAMBoard?

Yes. While the ADS1115V2EVM-PDK is optimized for use with the PAMBoard, the ADS1115EVM plug-in module supports direct MCU integration via pin headers J1–J4. These headers expose I²C (SCL/SDA), ALERT/RDY, power, and ground - matching the pinout in Table 3-1. Users can bypass the PAMBoard entirely and interface the ADS1115V2EVM-PDK with any I²C-capable host MCU, retaining full register access and configuration capability without GUI dependency.

What supply voltage options does the ADS1115V2EVM-PDK support for the ADS1115 device?

The ADS1115V2EVM-PDK supports two VDD supply options for the ADS1115: 3.3 V or 5 V, selected via jumper JP1. When JP1 is in the top position, the ADS1115 operates at 3.3 V; bottom position selects 5 V. The onboard LDO regulators derive both rails from USB 5 V, ensuring clean, stable power. Input voltage limits remain VDD + 0.3 V and GND – 0.3 V - critical for protecting the ADS1115 during evaluation.
