Product details
Overview
ADS8555EVM-PDK from Texas Instruments is a modular evaluation platform for the ADS8555 6-channel, 16-bit simultaneous-sampling SAR ADC - featuring ±12 V true bipolar analog inputs, dual digital interfaces (parallel and SPI), and programmable internal voltage reference. It supports full performance characterization including SNR, THD, SFDR, SINAD, and ENOB via time- and frequency-domain analysis tools.
For engineers reviewing the ADS8555EVM-PDK datasheet, ADS8555EVM-PDK pinout, ADS8555EVM-PDK application, or ADS8555EVM-PDK equivalent, this module enables rapid validation of high-voltage, multi-channel data acquisition systems in industrial test equipment, power quality analyzers, and motor control feedback loops.
Technical Context
The ADS8555EVM-PDK implements a two-board architecture: an ADC board hosting the ADS8555SPMR IC and precision analog signal conditioning circuitry, and a separate Precision Host Interface (PHI) controller board that translates USB 2.0 to parallel/SPI digital communication. The system supports hardware-mode (static pin configuration) and software-mode (SPI register programming) device control.
Analog interface includes six SMA-connected input channels with configurable op-amp buffers (noninverting, gain = 1 V/V default), jumper-selectable internal/external voltage reference (REF5025AIDGKR), and decoupling per ADS8555 datasheet recommendations. Power is derived from external ±15 V lab supplies (regulated to ±12 V HVDD/HVSS and 5 V AVDD) and USB (3.3 V BVDD).

FAQ
What is the ADS8555EVM-PDK used for?
The ADS8555EVM-PDK is a complete evaluation system for the ADS8555 6-channel, 16-bit simultaneous-sampling SAR ADC. It enables engineers to validate dynamic performance metrics (SNR, THD, SFDR, SINAD, ENOB), verify analog front-end design, configure digital interfaces (parallel/SPI), and assess true bipolar ±12 V input behavior - all using included hardware, cables, and Windows-based GUI software.
Does the ADS8555EVM-PDK support other ADCs besides the ADS8555?
Yes - the ADS8555EVM-PDK is pin-compatible with the ADS8556, ADS8557, and ADS8558. By desoldering the ADS8555SPMR and replacing it with one of these devices, then reprogramming the on-board EEPROM via the GUI's "Load EEPROM" tool, users can evaluate the full family without hardware redesign.
What power supplies are required to operate the ADS8555EVM-PDK?
The ADS8555EVM-PDK requires external ±15 V low-noise lab supplies connected to screw terminal J1 to generate HVDD (+12 V), HVSS (−12 V), and AVDD (5 V) via onboard LDOs (TPS7A3001 and TPS7A4700). BVDD (3.3 V) is supplied via USB from the PHI controller - no additional digital supply is needed.
How is analog input signal conditioning handled on the ADS8555EVM-PDK?
The ADS8555EVM-PDK provides six independent analog input paths, each with an OPA209AIDBVR op-amp configured as a noninverting unity-gain buffer by default. Jumpers JP00–JP05 allow bypassing the amplifier to connect signals directly to the ADC inputs. Input range is configurable via hardware pins or SPI register settings, supporting true bipolar operation up to ±12 V.
Can the ADS8555EVM-PDK be used without installing proprietary software?
No - the ADS8555EVM-PDK requires the dedicated Windows GUI software provided by Texas Instruments, which includes LabVIEW™ Runtime Engine dependencies, FPGA firmware loading for the PHI controller, and EEPROM configuration utilities. The GUI enables real-time data capture, FFT spectral analysis, register-level control, and hardware setup verification - none of which are accessible via generic USB enumeration.
