Texas Instruments ADS1282EVM-PDK

Overview

ADS1282EVM-PDK from Texas Instruments is an evaluation kit comprising the ADS1282EVM evaluation board, MMB0 motherboard, and ADCPro™ software for evaluating the ADS1282 - a 32-bit delta-sigma analog-to-digital converter with 2 differential inputs, 4.096 MHz onboard crystal oscillator, and SPI/I²C digital interface. It supports unipolar/bipolar operation, ±10V analog supplies, and real-time data acquisition in geophysical, seismic, and precision instrumentation applications.

For engineers reviewing the ADS1282EVM-PDK datasheet, ADS1282EVM-PDK pinout, ADS1282EVM-PDK application, or ADS1282EVM-PDK equivalent, this page delivers verified technical context, key specifications, supply chain availability, manufacturer background, and targeted FAQs - all grounded in TI's official SBAU144D User's Guide and hardware documentation.

Technical Context

The ADS1282EVM-PDK integrates the ADS1282EVM (featuring OPA1632 input buffers, REF5050/REF5025 voltage references, and dual-supply support) with the MMB0 motherboard - a TMS320VC5507-based DSP platform with USB connectivity and 16MB SDRAM. The system uses NI-VISA and USBStyx drivers to enable host PC communication.

Digital control is implemented via J5 header (3.3V CMOS/SPI/I²C), while analog signals route through J6 (differential AINP1/AINN1, AINP2/AINN2) and power is supplied via J8 (+VA/–VA, +5VA, DGND, AGND). Clocking defaults to the onboard 4.096 MHz crystal when used in PDK mode, with jumper J3 set to DVDD.

FAQ

What is the ADS1282EVM-PDK and how does it differ from the standalone ADS1282EVM?

The ADS1282EVM-PDK is a complete evaluation kit that includes the ADS1282EVM board, MMB0 motherboard, and ADCPro™ software. Unlike the standalone ADS1282EVM - which requires external host interface - the ADS1282EVM-PDK enables immediate PC-based evaluation via USB using the integrated TMS320VC5507 DSP on the MMB0. This eliminates the need for custom firmware or interface hardware during initial characterization of the ADS1282.

Which software is required to operate the ADS1282EVM-PDK, and what OS versions are supported?

The ADS1282EVM-PDK requires ADCPro™ software (v1.x) and two driver packages: NI-VISA for USB enumeration and USBStyx for firmware loading and real-time communication. Official support is limited to Microsoft Windows XP only; Windows Vista and later versions are not compatible per TI's SBAU144D documentation. The software provides scope, FFT, histogram, and calibration tools tailored for the ADS1282's 32-bit output format.

What power supplies are mandatory for proper operation of the ADS1282EVM-PDK?

The ADS1282EVM-PDK requires three essential power domains: +10V and –10V analog supplies (J8.1/J8.2) for the OPA1632 buffers and ADS1282 core, +5VA (J8.3) for analog circuitry, and +3.3VD (J8.9) for digital logic. The MMB0 also needs +5V via barrel jack J2 or terminal block J14. Bipolar mode adds a –5VA requirement. All grounds (AGND/DGND) must be properly connected per Figure 4 default jumper settings.

How is clocking configured on the ADS1282EVM-PDK, and why is the 4.096 MHz oscillator critical?

In ADS1282EVM-PDK mode, jumper J3 must be set to DVDD to enable the onboard 4.096 MHz crystal oscillator as the primary clock source for the ADS1282. This frequency is required for deterministic timing alignment with ADCPro's sampling engine and ensures correct recognition of the EVM by the software. Using an external clock (e.g., via J5.19 EXTCLK) is possible but disables PDK auto-detection and requires manual configuration outside the standard workflow.

Can the ADS1282EVM-PDK be used without the MMB0 motherboard?

No - the ADS1282EVM-PDK is a fixed-kit configuration that depends on the MMB0 for USB connectivity, real-time data streaming, and firmware execution. The standalone ADS1282EVM board (sold separately) lacks onboard processing and must be interfaced with external controllers (e.g., HPA-MCU or 5-6K Interface EVMs) or custom host systems. The PDK label explicitly denotes the bundled MMB0 + software + EVM assembly, and TI does not offer the MMB0 separately.
