Texas Instruments ADS8317EVM-PDK

Overview

ADS8317EVM-PDK from Texas Instruments is a production-ready evaluation kit for the ADS8317 - a 16-bit, 500-kSPS, serial-output SAR ADC in an MSOP-8 package. It includes the MSOP-8EVM evaluation board, MMB0 DSP-based motherboard, USB interface, onboard 2.5-V reference and buffer, and ADCPro™ software for real-time data acquisition and spectral analysis in precision sensor and instrumentation applications.

For engineers reviewing the ADS8317EVM-PDK datasheet, ADS8317EVM-PDK pinout, ADS8317EVM-PDK application, or ADS8317EVM-PDK equivalent, this kit delivers validated analog input conditioning, configurable digital I/O voltage (1.8 V to 5 V), jumper-selectable reference sourcing (onboard or external), and full support for continuous/clockstop/stretched-SCLK timing modes per the ADS8317 device specification.

Technical Context

The ADS8317EVM-PDK implements a modular two-board architecture: the MSOP-8EVM hosts the DUT ADC socket (U1), analog input header J1, digital control header J2, and configurable power/reference jumpers (JMP1–JMP6); the MMB0 motherboard provides TMS320VC5507 DSP processing, 16 MB SDRAM, USB 2.0 host interface, and programmable +5VA/+5VD/+3.3VD supply routing.

Digital interface signals include CS (jumper-configurable between FS and dedicated CS), SCLK, SDO, and frame-sync return lines; analog interface supports single-ended or differential input via J1.2/4, with external reference injection at J1.20 and AGND/DGND isolation managed by JMP4.

FAQ

What is the ADS8317EVM-PDK used for?

The ADS8317EVM-PDK is a complete evaluation system for the ADS8317 16-bit, 500-kSPS SAR ADC. It enables engineers to characterize dynamic performance (SNR, THD, SFDR), validate analog front-end design, verify timing behavior across clock modes (continuous, clockstop, stretched-SCLK), and integrate the ADS8317 into sensor signal chains using ADCPro software on Windows XP.

Does the ADS8317EVM-PDK support external reference sources?

Yes, the ADS8317EVM-PDK supports external reference sources via J1.20 (REF(+)) and J1.18 (REF(–)). Jumpers JMP5 and JMP6 control selection: JMP5 pins 2–3 enable external reference input, and JMP6 pins 2–3 route +VADC as reference. The onboard 2.5-V reference (U2/U4) remains active unless explicitly disabled per the ADS8317EVM-PDK User's Guide.

Which ADCPro software version is required for the ADS8317EVM-PDK?

The ADS8317EVM-PDK requires ADCPro software v1.x, specifically the ADS8317EVM-PDK plug-in (e.g., ads8317evm-pdk-plugin-1.0.0.exe). It runs exclusively on Windows XP and installs USB drivers during first connection. Later ADCPro versions do not support this legacy kit, and no Windows 10/11-compatible update exists per TI documentation SBAU140A.

Can the ADS8317EVM-PDK operate without the MMB0 motherboard?

No - the ADS8317EVM-PDK is a bundled kit that includes both the MSOP-8EVM board and the MMB0 motherboard. While the MSOP-8EVM board alone can be used standalone with external controllers, the ADS8317EVM-PDK designation refers specifically to the integrated kit with MMB0, USB interface, and ADCPro plug-in support. TI does not sell the MMB0 separately.

What power supplies are needed for the ADS8317EVM-PDK?

The ADS8317EVM-PDK requires +5 V for the analog section (applied to J3.3 or TP5) and +1.8 V to +5 V for the digital section (selected via JMP3). Power may be delivered via the included AC adapter (6–9 V DC, sleeve-negative/tip-positive) to MMB0 J2, or via lab supply to terminal block J14 (+5VD/GND). LED D2 indicates proper +3.3 V operation on the MMB0, not EVM-level supply status.
