Texas Instruments TLA2024EVM-PDK

Overview

TLA2024EVM-PDK from Texas Instruments is a fully assembled evaluation platform combining the TLA2024 Evaluation Module (EVM) and PAMBoard motherboard to enable rapid functional validation of the TLA2024 12-bit ultra-small, low-power ADC. It supports four single-ended or two differential analog inputs, I²C configuration, full-scale ranges from 256 mV to 6.144 V, and USB-powered operation with 3.3 V/5 V selectable supply via JP1 jumper.

For engineers reviewing the TLA2024EVM-PDK datasheet, TLA2024EVM-PDK pinout, TLA2024EVM-PDK application, or TLA2024EVM-PDK equivalent, this platform delivers out-of-box analog-to-digital evaluation with GUI-driven capture, FFT/time-domain analysis, register-level control, and hardware-level signal conditioning including RC filters for both single-ended (67.9 kHz cutoff) and differential (3.4 kHz cutoff) input modes.

Technical Context

The TLA2024EVM-PDK implements a host-bridged architecture: the PAMBoard serves as a USB-to-I²C bridge, translating PC commands into I²C transactions targeting the TLA2024 ADC (U1) and preprogrammed EEPROM (U3). Level-shifting circuitry (U2) enables interoperability between the PAMBoard's 3.3 V logic and the TLA2024's configurable 3.3 V or 5 V VDD supply.

Analog inputs are routed through onboard RC filters-single-ended paths use 10 kΩ + 2.35 nF (67.9 kHz), while differential pairs AIN0–AIN1 and AIN2–AIN3 use 10 kΩ + 4.7 nF (3.4 kHz); optional AIN1–AIN2 differential mode requires manual capacitor C6 placement. Power delivery includes USB-sourced 5 V, DC/DC boost to 5.5 V, and LDO regulation to clean 5 V and 3.3 V rails.

FAQ

What is the TLA2024EVM-PDK and how does it differ from the TLA2024 IC?

The TLA2024EVM-PDK is an evaluation platform-not an IC-that integrates the TLA2024 12-bit ADC with the PAMBoard motherboard to provide USB connectivity, GUI software, analog signal conditioning, and power management. Unlike the bare TLA2024 IC (SBAS846), the TLA2024EVM-PDK includes headers, terminal blocks, RC filters, level shifters, and EEPROM for plug-and-play evaluation. The TLA2024EVM-PDK requires no external MCU to operate its GUI-driven workflow.

Does the TLA2024EVM-PDK support differential input measurements?

Yes, the TLA2024EVM-PDK supports two differential input pairs-AIN0–AIN1 and AIN2–AIN3-with onboard RC filtering optimized for 3.4 kHz cutoff. AIN1–AIN2 differential mode is possible but requires manual placement of a 47-nF capacitor at C6 per the schematic. All differential configurations are configured via the TLA2024EVM-PDK GUI under Capture Settings > MUX selection, and validated by the TLA2024's internal programmable multiplexer.

How is the TLA2024EVM-PDK powered and what voltage options does it support?

The TLA2024EVM-PDK draws power from a standard USB port (5 V), which feeds a DC/DC converter and dual LDO regulators on the PAMBoard to generate clean 5 V and 3.3 V rails. The TLA2024 ADC itself operates at either 3.3 V or 5 V, selected via jumper JP1. This dual-voltage capability ensures compatibility with both low-noise 3.3 V systems and higher-headroom 5 V sensor interfaces without redesigning the evaluation setup.

What software is required to operate the TLA2024EVM-PDK?

The TLA2024EVM-PDK uses a web-based GUI that runs in Chrome or Firefox browsers and requires two mandatory components: the TI Cloud Agent desktop application and a browser extension. These enable secure USB CDC/Bulk communication between the PC and PAMBoard. No local installation of drivers or standalone executables is needed-the GUI loads directly from ti.com, and all data capture, FFT, register access, and configuration occur within the browser environment.

Can the TLA2024EVM-PDK be used without the PAMBoard?

No-the TLA2024EVM-PDK is defined as the combined system of the TLA2024 EVM and PAMBoard; they are functionally inseparable in this kit. However, the TLA2024 EVM module alone (without PAMBoard) can be interfaced to an external host MCU via its pin headers (J1–J4), using the pinout documented in Table 3-1 of the user's guide. That configuration requires custom firmware and is outside the scope of the TLA2024EVM-PDK's intended out-of-box GUI operation.
