Texas Instruments ADS8353Q1EVM-PDK

Overview

ADS8353Q1EVM-PDK from Texas Instruments is an evaluation module and performance demonstration kit (PDK) for the ADS8353-Q1 16-bit, dual-channel, simultaneous-sampling SAR ADC. It integrates the ADS8353-Q1 device, OPA320-Q1 input drivers, TPS7A47-Q1 low-noise LDO, REF34-Q1 voltage reference option, and a precision host interface (PHI) controller board with USB 2.0 connectivity. Designed for automotive-grade signal acquisition, it supports single-ended and pseudo-differential analog inputs up to 600 kSPS with ≤83 dB SINAD and ≤–100 dB THD at 2 kHz.

For engineers reviewing the ADS8353Q1EVM-PDK datasheet, ADS8353Q1EVM-PDK setup, ADS8353Q1EVM-PDK GUI operation, or ADS8353Q1EVM-PDK spectral analysis tool, this page provides verified hardware configuration details, jumper settings for input mode selection, USB-powered operation requirements, LabVIEW-based software workflow, and real-world dynamic performance validation methods using external signal sources meeting SNR ≥90 dB and THD ≤–115 dB.

Technical Context

The ADS8353Q1EVM-PDK comprises two main PCBs: the ADS8353-Q1EVM board hosting the SAR ADC, OPA320-Q1 unity-gain buffers, 49 Ω/3.3 nF anti-aliasing filters, and TPS7A47-Q1 5.3-V analog supply; and the PHI controller board providing USB-to-SPI/I²C bridging, 3.3-V digital power, and EEPROM-based platform initialization. Communication occurs via SPI to the ADC and I²C to the BR24G32FVT-3AGE2 EEPROM.

Input configuration is hardware-selectable via jumpers J6/J7 and JP6/JP7 for single-ended (AINM grounded) or pseudo-differential (AINM driven by VREF/2 or VREF) modes. The GUI enables real-time control of SCLK frequency, sampling rate, channel mode (A/B/both), input range, reference source (internal 2.5 V or external), and data format - all persisting across time-domain, spectral, and histogram analysis tools.

FAQ

What is the primary purpose of the ADS8353Q1EVM-PDK?

The ADS8353Q1EVM-PDK is a complete evaluation system for the ADS8353-Q1 automotive SAR ADC. It includes hardware (ADS8353-Q1EVM board + PHI controller), USB cable, and Windows-based GUI software enabling full characterization - including time-domain capture, spectral analysis (SNR, THD, SFDR), and histogram-based effective resolution measurement - without external power supplies or additional instrumentation.

Does the ADS8353Q1EVM-PDK require an external power supply?

No. The ADS8353Q1EVM-PDK is fully USB-powered via the included A-to-micro-B cable. The PHI controller board delivers regulated 5.3 V (from TPS7A47-Q1) to the analog section and 3.3 V to the digital section. No bench power supply or external voltage sources are needed for basic operation or performance testing.

How do I configure the ADS8353Q1EVM-PDK for pseudo-differential input mode?

To configure pseudo-differential mode on the ADS8353Q1EVM-PDK, short pins 1 and 2 of jumpers J6 and J7, and short pins 1 and 2 of JP6 and JP7. This routes VREF/2 to the AINM inputs. Confirm the setting in the GUI under "ADC Input Configuration" - select "Pseudo-differential" and "0 V to VREF" or "0 V to 2 × VREF" range as required. Default jumper states are open.

Which software components are required to operate the ADS8353Q1EVM-PDK?

The ADS8353Q1EVM-PDK requires three software elements: (1) the EVM GUI installer (provided by TI), (2) the LabVIEW Run-Time Engine (automatically prompted during install), and (3) the USB device driver installed via the Device Driver Installation Wizard. All are bundled in the official TI ADS8353Q1EVM-PDK Tool Folder and validated for Windows 7 (64-bit).

Can the ADS8353Q1EVM-PDK evaluate dynamic performance metrics like SNR and THD?

Yes. The ADS8353Q1EVM-PDK's Spectral Analysis tool performs FFT-based dynamic evaluation using a 7-term Blackman-Harris window. To achieve valid results, the external 2-kHz sine-wave source must meet SNR ≥90 dB and THD ≤–115 dB. Alternatively, TI's Precision Signal Injector EVM can be used as a compliant low-noise, low-distortion stimulus source.
