Texas Instruments ADS8320EVM-PDK

Overview

ADS8320EVM-PDK from Texas Instruments is a complete evaluation kit for the ADS8320 - a 16-bit, 100-kSPS, serial-output SAR analog-to-digital converter in an MSOP-8 package. It includes the MSOP-8EVM evaluation board, MMB0 motherboard with TMS320VC5507 DSP and USB interface, onboard 2.5V reference (U2), buffered analog input path, and ADCPro™ software for data acquisition and analysis.

For engineers reviewing the ADS8320EVM-PDK datasheet, ADS8320EVM-PDK pinout, ADS8320EVM-PDK application, or ADS8320EVM-PDK equivalent, this kit enables rapid functional validation, dynamic performance characterization (SNR, THD, SFDR), and interface timing verification of the ADS8320 under real-world analog signal conditioning and host controller conditions.

Technical Context

The ADS8320EVM-PDK implements a modular, two-board architecture: the MSOP-8EVM hosts the ADS8320 socket and analog front-end (onboard 2.5V reference U2, buffer U4, configurable J1 analog header), while the MMB0 provides digital control via its TMS320VC5507 DSP, 16MB SDRAM, and USB 2.0 interface. Power is supplied via +5VA (analog) and selectable +1.8V/+3.3V/+5VD (digital) through J3.

Digital communication uses SPI-compatible signals (CS, SCLK, SDO) routed through J2, with jumper-configurable chip select (JMP2) and frame sync (FS) support for DSP interfacing. ADCPro software controls clock modes - Continuous Clock–Max SCLK, Clockstop Mode–Max SCLK, and Continuous Mode–Stretched SCLK - each enforcing precise timing alignment per ADS8320's 24-cycle serial interface requirement.

FAQ

What is the ADS8320EVM-PDK used for?

The ADS8320EVM-PDK is a complete evaluation kit for the ADS8320 16-bit, 100-kSPS SAR ADC. It enables engineers to validate dynamic performance (ENOB, SNR, THD), verify SPI timing compliance, characterize analog input behavior with onboard reference and buffering, and develop firmware drivers using the included ADCPro software and MMB0 DSP platform. The ADS8320EVM-PDK supports both standalone bench testing and integration into larger system prototypes.

Does the ADS8320EVM-PDK include the ADS8320 IC?

No, the ADS8320EVM-PDK does not include the ADS8320 IC pre-installed. It provides a socketed MSOP-8 footprint (U1) on the MSOP-8EVM board for user-insertion of the ADS8320 or other compatible 8-pin MSOP ADCs such as the ADS8321, ADS8324, ADS8325, or ADS8326. Users must procure the ADS8320 separately and mount it before operation.

Which software is required to operate the ADS8320EVM-PDK?

The ADS8320EVM-PDK requires ADCPro™ software (v1.x), which runs exclusively on Windows XP. It includes a dedicated ADS8320EVM-PDK plug-in that configures sample rate, reference voltage, and clock mode (Continuous Clock–Max SCLK, Clockstop Mode–Max SCLK, or Continuous Mode–Stretched SCLK). Driver installation occurs automatically via Windows Found New Hardware Wizard upon first USB connection.

Can the ADS8320EVM-PDK evaluate other ADCs besides the ADS8320?

Yes, the ADS8320EVM-PDK is part of the modular MSOP-8EVM platform and supports multiple 14- to 16-bit, single-channel, serial-output ADCs in MSOP-8 packages. Confirmed compatible devices include ADS8321, ADS8324, ADS8325, and ADS8326 - all listed in TI's SBAU140A User's Guide. Each requires its own ADCPro plug-in and may need jumper or reference configuration adjustments per its datasheet.

What power supplies are needed for the ADS8320EVM-PDK?

The ADS8320EVM-PDK requires +5V analog (for reference and ADC analog section) and a selectable digital supply (+1.8V, +3.3V, or +5V) applied via J3 on the MSOP-8EVM board. Power is delivered either through the MMB0's barrel jack (6–9V DC, sleeve-negative) or terminal block J14 (+5V DC). Onboard jumpers (JMP1, JMP3) configure ADC supply and I/O voltage levels to match the installed device's requirements.
